The Psychology Behind Games by Anders Hejdenberg

The Psychology Behind Games

Introduction

We are all familiar with the feeling we have when we are completely caught up in a great game. The state where we are completely focused on playing, and all other things become irrelevant. This article is about that feeling - why we get it when we play games, and how we can design games that give us more of it.

In the first part of the article we will look at how we function as humans; what our drives are and why we enjoy certain activities. At first this may seem a bit unrelated to games, but soon we will see that the actual game is only what we see on the surface - what we experience is something else completely. In order to fully understand why we enjoy certain games, we need to look at what lies below the surface and try to see them the way our mind sees them.

The second part of the article focuses on how games can be designed to cater to the player's needs, interests and abilities. We look at the importance of understanding your target audience, and how games can be built to adapt to the person who is playing. People both have differences and similarities to each other, and the game's design needs to reflect that.

Overall, the purpose of this article is to provide a better understanding of why we enjoy certain games so much and how to design games that focus on those aspects. My view is that if we can see games the way our mind sees them, we can perhaps get some new ideas on how to design our games to be more fun for the player.

Part One - Why brains love games

Needs and motivations


Maslow's pyramid of needs.

As humans, we have developed many needs over time that are closely related to our survival, existence and evolution. In a way, everything we do in our daily lives is in either a direct or an indirect way related to these needs. Abraham Mallow was the first to summarize the research related to human behavior by creating a list of human needs and sorting them in hierarchic order. Maslow's hierarchy of needs was based in two groups: deficiency needs and growth needs. Within the deficiency needs, each lower need must be met before moving on to the higher needs. If at a later time a lower need is detected, the individual will act to fulfil that need before resuming focus on higher needs. When the deficiency needs are fulfilled, the individual's attention will turn towards the growth needs.

Deficient needs:

1. Physiological needs: To breathe, drink, eat, sleep, bodily comforts, etc.

2. Safety and security needs: To feel safe, out of harms way, protected, to live in a safe neighborhood, to know ahead what the plans are.

3. Belongingness and love needs: To affiliate with others, be accepted, be part of a group, to love and be loved, to have a family, to be social.

4a. Lower esteem needs: To be respected, to get attention, to have status, power, reputation, dignity, to express oneself through words, clothes, or self-creations.

4b. Higher esteem needs: To have self-respect, to be competent, to achieve independence and freedom. 

Growth needs:

5. Cognitive needs: To know, to understand, to explore, to seek adventure, to experience new things, to travel, to feel excitement.

6. Self-actualization needs: To realize one's potential, to be all that you can be.

7. Transcendence: To help others to self-fulfilment and realize their potential.

Rewarding good behavior

In order to make sure that we listen to our needs, evolution has developed our brain with designated reward areas that serve to reinforce healthy behavior, such as drinking when we are thirsty. Dopamine, a neurotransmitter associated with pleasant feelings, is released by these reward areas to encourage the body to repeat these behaviors. This is the reason why fulfilling needs is often associated with feelings of pleasure. It could be said that our body helps us to distinguish positive behavior by rewarding it with an induction of pleasurable brain chemicals.

When we look at lower needs, things seem to be quite simple: we are hungry, we eat, and we get rewarded. But when it comes to rewarding higher needs - like gaining the respect of others for example - things tend to get a lot more complex. The higher needs are not based around our physical needs, but rather around the psychological needs. So how can there be a specific behavior or activity to reward, if everyone has a different view of what the needs are?

The interesting fact of the matter is that it is completely up to our own view of what respect is to decide whether we have accomplished what we should and deserve a reward. Quite simply, from an objective standpoint it does not really matter what we do, how we do it, or why - as long as we feel that we are doing the right thing, for the right reasons, and getting good results, we will get our fix of dopamine. For example, there is no difference between winning the lottery and thinking you have won the lottery - they are both just as fun up until you start trying to spend the money. 

Measuring results

It can be said that on a personal level - as we perceive it - the ultimate goal for all our activities is to get pleasure and/or avoid pain. If we have an activity where we can conclude that the possible gain in pleasure outweighs the possibility of failure and pain, we will most likely want to do it. The amount of pleasure or pain that is then derived from the activity relies on how much we've learned (was it interesting to me?), our subjective view of the activity itself (was this okay for me to do?) and the measurement of its success (did I do well?).

The problems we face in our modern society is that our options are so plentiful, the boundaries between right and wrong are not always clear, and we can seldom get a good measurement of the results of our actions. This means that it can many times be difficult for us to decide what we should be doing, and perhaps even more difficult to get the pleasure from knowing that we have done something well. We tend to measure ourselves against other people, and there is always someone out there that appears to be smarter, happier, more talented or just plain better looking. So what can we do to ensure that our activities give us pleasure? 

Games

Games are specifically designed to deal with this issue - and not just videogames, but all types of games. Games can be played against other people, against yourself, against a computer, or perhaps even against the forces of nature - but what they all have in common is that they have set goals with set rules that you have to follow in order to play. This makes it much easier for us to decide what to do and makes measuring the outcome much simpler. We also have the learning aspect in games since in most games we will have to keep improving our skills in order to beat the competition (or our previous record).

Game experiences

Roger Caillois is the theorist behind the book Man, Play, and Games. In his book, Caillois proposed a useful system of classifying the different types of experiences that are present in games. A game can include just one or all of these different types of experiences.

1. Competition

Activities where players use their skill to overcome the challenge that their opponents offer. The pleasure lies in developing your skills to outmaneuver the opposition. Football and chess are examples of such activities.

2. Chance

Activities where elements of chance can have an impact on the outcome of the game. The pleasure lies in finding ways to minimize the impact of the element of chance, and the excitement of trying to guess the outcome. Games that are based on chance can also give players the illusion of being able to control or foresee the future. Slot machines and lotteries are examples of such activities.

3. Vertigo

Activities that alters the state of mind by disrupting the normal perception of the world, resulting in a pleasurable state of dizziness. Roller coaster rides and skydiving are examples of such activities.

4. Make-Believe

Activities where we create alternate realities in which we are not bound by the constraints of the real world. The pleasure lies in assuming various characteristics and abilities that we do not possess in our normal life. In this state of make-believe we can feel as if we actually possessed the powers of what we have chosen to assimilate. Role-playing, theatre and reading books are examples of such activities.

Pleasurable activities

So if playing games is an activity that can give us pleasure - why do certain games give us more pleasure than others? Mihály Csíkszentmihályi is considered by many to be the leading researcher in the field of positive psychology. Csíkszentmihályi has developed the notion of "flow" - a state that he describes as "being completely involved in an activity for its own sake. The ego falls away. Time flies. Every action, movement, and thought follows inevitably from the previous one, like playing jazz. Your whole being is involved, and you're using your skills to the utmost."

People who have played games can most likely relate to this feeling. And most people will agree that this feeling is very pleasurable. But what is it that makes us reach this state of mind? Mr. Csíkszentmihályi has come up with a list of eight things that are associated with "flow" or "being in the zone" as it is often described. 

1. It's an activity that we feel that we can perform - a challenge that requires skill

Any activity provides us with a number of options - or challenges - that require a certain skill to do. If we don't have the required skill for the activity, the challenge will easily become frustrating or feel meaningless. Pleasure comes in the area between boredom and anxiety at the distinct moment where our options are in line with our abilities.

Playing a game of chess against an evenly matched opponent is a good example of this - if they were much better than we were, it could feel meaningless since we cannot really affect the outcome. If we were much better than they were, it could be boring since there is no challenge in it for us.

2. We need to be able to concentrate on what we are doing

When a person's skill is needed to perform a task their focus will be completely absorbed with what they're doing. We regress into a state where our actions become spontaneous and we stop being aware of ourselves as parted from what we are doing. In order to be able to enter and then remain in this state it is important that there are no distractions - neither from outside of the activity or from the activity itself.

A common distraction in many games is difficult controls. If the controls are not simple or intuitive enough for us to be able to do what we want to do, we will constantly be distracted from what we are doing. Our focus will turn toward the controls instead of the game.

3. We need to have clear goals for our activity

Without a clear goal you have little means of judging whether or not we are making any progress. The pleasure does not necessarily lie in reaching the goal itself - it is only the end of the ruler by which we measure our progress. It is also important that goals are set at a level where we need to invest our skills to reach the goal - otherwise the goal will become meaningless.

For example, if our goal were just to reach the finish line in a racing game we would not need to pay much attention to be successful. If the goal would instead be to reach the finish line within a short time-frame, the task would perhaps require our complete attention.

4. We need to get constant feedback on our progress

In order to be able to judge if our activities are fruitful, we need to get some form of feedback on our efforts. We may fail in certain attempts to reach our goals, but if we get enough feedback along the way, we can still feel that we are on the right track and that our invested efforts are paying off. Feedback is not only about being told that we are doing well. It is just as important that the activity is laid out in a way where we can constantly judge our own progress.

In many fighting games, there is an indication of the opponent's health above their character. This is a good way to provide us with feedback on how well we are doing, and to help us develop our technique so that our attacks deal the most amount of damage. 

5. We act with a deep involvement that frees us from our everyday worries

In order to be deeply involved it is important that the activity has not been forced upon us against our will. When we act out of free will with deep involvement, we forget about all the unpleasantries in life. The activity demands such a full concentration that there is no room for us to reflect upon anything else.

Even though playing games is usually not forced upon us, some elements in games can become boring or repetitive after a while. When they do, we can easily become less involved in the game since we feel that we are being forced to do these things in order to progress. 

6. We need to exercise control over our environment

In a structured activity we can often get a feeling of control. We are free from the anxiety of losing control that is so common in our daily lives - we are not afraid of failing. The important thing is that the activity is designed so that it allows us to develop such a great skill that the risk of failure is eliminated. It's not about having control, but about exercising control. It is only when the outcome is uncertain and we feel that we can affect the outcome that we experience that we are in control.

If the game contains elements that the player cannot control but that affect the outcome of the game, the player will not be able to exercise control. Games that allow the player to exercise full control will almost always end with the most skilled player winning.

7. We become less self-absorbed

When we concentrate fully on an activity there is no room for self-reflection. All our attention is used to perform the activity. Afterwards, we can look at ourselves and notice that we have grown from the experience - our mind has been enriched with new skills and new accomplishments.

8. Our perception of time is altered

Our perception of time is mainly based on perceived changes around us, but when the activity demands our full concentration there is no room to register anything but the activity itself. This can make days feel like hours and hours like minutes. 

Summary


StarCraft

Games are activities that we have specifically designed to maximize the amount of pleasure we get from them. Games are our way of having fun, regardless of our current life situation. In games, we do not have to abide to the restrictions of the ordinary world. We can create our own rules where our specific talents can be recognized and rewarded - talents that would perhaps otherwise go unnoticed.

However, games are not just an activity - they are also many other things. This goes especially for videogames. For example, the game StarCraft is not just about managing resources and planning strategic moves with your game pieces. It is also about being a military leader in a distant future, it is about stopping a flood of aliens that are trying to take over your world, it is about treachery and deceit, and it is about doing the right thing and becoming a hero.

In the second part of this article, we will look at videogames specifically and see how we can design games that are adjusted after the player's needs and desires.

The Easiest Way To Live Longer

By Lisa Collier Cool
ก.ย. 11, 2012
 
Did you know that every minute you walk can extend your life by 1.5 to 2 minutes? In addition, many studies show that people who walk regularly live longer, weigh less, have lower blood pressure, and enjoy better overall health than non-walkers.
Ready to lace on your shoes? If you want to add to the amount of walking you do, just clip on a pedometer. That simple action actually increases your physical activity by over 2100 steps per day, a review that pooled data from 26 studies found.
Here's a look at ten benefits of walking.

 

Walking Increases Your Lifespan

Walking more than an hour a day improves life expectancy significantly, a 2011 study showed. The researchers looked at 27,738 participants between the ages of 40 and 79 over a 13-year period. Surprisingly, their lifetime medical costs did not increase—even though they lived longer.
"An increase in walking time at the population level would bring about a tremendous change in people's health and medical cost," the study authors wrote.

 

Walking Wards Off Diabetes

Just thirty minutes of walking a day can prevent diseases such as type 2 diabetes, a 2002 study looking at both overweight and average weight men and women in a population at high risk for the disease showed.
If you already have diabetes, walking is helpful for you, too. A mile or more daily cuts your risk of death from all causes in half, according to a 2007 study.

 

Walking Keeps Your Mind Sharp

Walking 72 blocks a week (around six to nine miles) helps increase grey matter, which in turn lowers the risk of suffering from cognitive impairment—or trouble with concentration, memory and thought, according to a study which looked at 299 seniors over a nine-year period.
Furthermore, walking five miles per week can provide some protection to the memory and learning areas of the brains of those already suffering from Alzheimer's disease or mild cognitive impairment, and lead to a slower decline in memory loss.

 

Walking Helps Lower Blood Pressure

Walking just 30 minutes a day, three to five days a week—even when the 30 minutes are broken into three ten-minute increments—has been found to significantly lower blood pressure.

 

Walking is Great for Bone Health

Putting one foot in front of the other for about a mile a day led to improved bone density in post-menopausal women, and slowed the rate of bone loss from the legs, according to a 1994 study. "It takes walkers four to seven years longer to reach the point of very low bone density, study leader Dr. Krall told the New York Times.

 

Walking Cuts the Risk of Stroke

Walking about 12.5 miles a week or more cut the risk of stroke in half, according to a study looking at over 11,000 Harvard University alumni with an average age of 58.

 

Walking Improves Your Mood

If you're feeling down in the dumps, walking is a quick and easy solution. Just thirty minutes on a treadmill reduces feelings of tension and depression, according to research published in the British Journal of Sports Medicine. In fact, the study found that walking lifted moods more quickly than anti-depressants did (and with fewer side effects).
And the more people walk, the better their mood and energy, says California State University Long Beach professor Robert Thayer, based on a study looking at 37 study participants over a 20-day period.

 

Walking Torches Calories

Just 20 minutes of walking a day will burn 7 pounds a year. The effects are even more dramatic when you add in some dietary changes as well.

 

Walking Improves Insomnia

Having trouble sleeping at night? Try taking a brisk 45-minute walk in the morning five days a week, and your sleep may improve significantly, according to research from the Fred Hutchinson Cancer Research Center in Seattle, which looked at women from the age of 50-74. (Walking in the evening, however, sometimes has the opposite effect—so keep an eye on when you're exercising and what your sleep patterns are.)

 

Walking is Good for the Heart

Women who took brisk walks for three or more hours per week reduced their risk of heart disease by 30-40 percent, according to an analysis of over 72,000 women aged 40-65, who were enrolled in the prospective Nurses' Health Study. As I reported recently, heart attacks kill more US women than men annually. However, the benefits of walking aren't limited to one gender. A different study showed that walking can cut the risk of coronary heart disease in half for men between the ages of 71 and 93.

Singapore banker becomes half-paralysed after neck

massage in China ( choose ladies with softer hands ) 

 SINGAPORE - After a particularly painful neck massage, a 40-year-old banker from Singapore suffered a stroke and became a paraplegic consequentially.
Mr Lin claims that his doctors suspect that the excessive force used in the massage broke a blood vessel and resulted in a stroke.
He is now deaf in one ear and is undergoing therapy to regain movement in the left half of his body, Chinese DailyLianhe Wanbao reported.
According to the paper, Mr Lin is an assistant director of a department in a bank, and was in China recently to visit some friends.
There, he visited a massage parlour to get a foot massage. Upon the therapist's recommendation, he decided to try a neck massage instead.

After the massage, he felt okay. But three days later, he suddenly felt a sharp pain in the left side of his head, and woke up to find that his left ear was deaf.
He also couldn't move the left side of his body, and was unsteady in his gait.
He recalled: "I felt very afraid. It all happened so fast, it was really like a bolt from the blue."

As he was not in condition to be moved, he could not return home immediately for treatment. Mr Lin was sent to a hospital in Hong Kong and hospitalised for about two weeks until doctors deemed him fit for a flight home.

Mr Lin told the Chinese Daily that his doctors suspect that when he underwent the neck massage, the massage therapist tore the vascular wall of an artery accidentally by using too much force.
The damage resulted in the blockage of the artery passage, causing the blood flow to be disrupted.
Recovery
According to his doctors, Mr Lin suffered vertebral artery dissection, which is a flap-like tear of the inner lining of the vertebral artery - a blood vessel that is located in the neck and supplies blood to the brain.
After the tear, blood enters the arterial wall and forms a blood clot, thickening the artery wall and often impeding blood flow. This can result in intermittent or permanent stroke symptoms such as difficulty speaking, impaired coordination and even vision loss.
According to medical resources, it can be caused by physical trauma to the neck, such as a car accident.
Currently, Mr Lin is undergoing treatment at TanTock Seng Hospital's rehabilitation ward.
Last month, he began a "walking" rehabilitation treatment, where he is assisted in walking back and forth along a set path. Doctors said this will help speed up the recovery process.
On August 24, Mr Lin was discharged from hospital. Although he is still easily fatigued, he is now able to walk without the need for crutches.
Other than Mr Lin's case, there have been reports in the media about people who have become paralysed after massages.
In 2006, a woman from Australia suffered a stroke after a company masseur gave her a massage at her workplace.
It is believed that similar to Mr Lin's case, the massage caused a blood vessel in her neck to tear, slowly blocking the blood supply to her brain.
Very real danger
Adjunct Associate Professor Hee Hwan Tak, Medical Director of the Centre for Spine & Scoliosis Surgery - a subsidiary of Singapore Medical Group - toldYourHealth that such a scenario is not only possible, it has happened in Singapore before.
"It it is possible to suffer a stroke if the massage is overzealous and the patient has pre-existing issues," said Prof Hee.
According to Prof Hee, this is because there are vertebral arteries in the neck that travel within a relatively confined space intimately related to the vertebrae.
As such, these vertebral arteries may be injured by excess manipulation of the area.
Possible injuries range from blood clots, the clot moving from the neck to the brain, and the dissection of the artery like Mr Lin

WELLBEING Part 2 - CAREER WELLBEING

 What's your answer to this question : Do you like what you do every day?

FROM ANOTHER ANGLE – If your answer to the question "What do you do?" describes something you find meaningful and fulfilling, you are likely to be thriving in Career Wellbeing.

Career Wellbeing

·         Most essential of the 5 elements

·         Career shapes your identity – a lot of who you are comes from what you do

·         It isn't about a fat pay cheque

·         It's about being happy and interested in your job which helps reduce work stress

·         It's enjoying weekdays as much as weekends

What encourages active work engagement OR Why shouldn't we enjoy work?

·         Having fun at work is getting the opportunity to use your strengths every day.

·         People who  have the opportunity to use their strengths are 6 times as likely to be engaged in their jobs

·         People who have the opportunity to use their strengths can work a full 40 hour week and not get burned out

·         People who  do not have the opportunity to use their strengths get burned out after just 20 hours of work per week

What's so dangerous about being disengaged at work?

·         Being disengaged at work appears to be a leading indicator of a subsequent clinical diagnosis of depression

·         When is work disengagement likely to occur?

o   If your manager ignores you, there is a 40% chance you will be actively disengaged

o   If your manager is at least paying attention – even if focusing on your weaknesses – there is a 22% chance you will be actively disengaged

o   If your manager is primary focusing on your strengths, there is a 1% chance you will be actively disengaged.

 

Three recommendations for boosting Career Wellbeing

1.       Every day, use your strengths

2.       Identify someone with a shared mission who encourages your growth.  Spend more time with this person.

3.       Opt into more social time with the people and teams you enjoy being around at work.

9 things that will disappear in our lifetime ...


9 Things That Will Disappear In Our Lifetime

Whether these changes are good or bad depends in part on how we adapt to them. But, ready or not, here they come ...


1.
The Post Office Get ready to imagine a world without the post office. They are so deeply in financial trouble that there is probably no way to sustain it long term. Email, Fastway, Fed Ex, and UPS have just about wiped out the minimum revenue needed to keep the post office alive. Most of your mail every day is junk mail and bills.

2.
The ChequeBritain is already laying the groundwork to do away with cheque by 2018. It costs the financial system billions of dollars a year to process cheques. Plastic cards and online transactions will lead to the eventual demise of the cheque. This plays right into the death of the post office. If you never paid your bills by mail and never received them by mail, the post office would absolutely go out of business.

3.
The NewspaperThe younger generation simply doesn't read the newspaper. They certainly don't subscribe to a daily delivered print edition. That may go the way of the milkman, butcher, baker and fruit and veg man. As for reading the paper online, get ready to pay for it. The rise in mobile Internet devices and e-readers has caused all the newspaper and magazine publishers to form an alliance. They have met with Apple, Amazon, and the major cell phone companies to develop a model for paid subscription services.

4.
The BookYou say you will never give up the physical book that you hold in your hand and turn the literal pages. Many said the same thing about downloading music from iTunes because they wanted hard copy CD.  When they discovered they get albums for half the price without ever leaving home to get the latest music they changed their minds. The same thing will happen with books. You can browse a bookstore online and even read a preview chapter before you buy. And the price is less than half that of a real book. Just think of the convenience! Once you start flicking your fingers on the screen instead of the book, you find that you are lost in the story, can't wait to see what happens next, and you forget that you're holding a gadget instead of a book.

5.
 The Land Line TelephoneUnless you have a large family and make a lot of local calls, you don't need it anymore. Most people keep it simply because they've always had it. But you are paying double charges for that extra service. All the cell phone companies will let you call customers using the same cell provider for no charge against your minutes

6.
 MusicThis is one of the saddest parts of the change story. The music industry is dying a slow death. Not just because of illegal downloading. It's the lack of innovative new music being given a chance to get to the people who would like to hear it. Greed and corruption is the problem. The record labels and the radio conglomerates are simply self-destructing. Over 40% of the music purchased today is "catalogue items," meaning traditional music that the public is familiar with. Older established artists. This is also true on the live concert circuit. To explore this fascinating and disturbing topic further, check out the book, "Appetite for Self-Destruction" by Steve Knopper, and the video documentary, "Before the Music Dies."

7.
 TelevisionRevenues to the networks are down dramatically. Not just because of the economy. Many people are watching TV and movies streamed from their computers. And they're playing games and doing lots of other things that take up the time that used to be spent watching TV. Prime time shows have degenerated down to lower than the lowest common denominator. Cable rates are skyrocketing and commercials run about every 4 minutes and 30 seconds. It's time for the cable companies to be put out of our misery. People will  choose what they want to watch online and through Netflix.

8.
 The "Things" That You OwnMany of the very possessions that we used to own are still in our lives, but we may not actually own them in the future. They may simply reside in "the cloud." Today your computer has a hard drive and you store your pictures, music, movies, and documents. Your software is on a CD or DVD, and you can always re-install it if need be. But all of that is changing. Apple, Microsoft, and Google are all finishing up their latest "cloud services." That means that when you turn on a computer, the Internet will be built into the operating system. So, Windows, Google, and the Mac OS will be tied straight into the Internet. If you click an icon, it will open something in the Internet cloud. If you save something, it will be saved to the cloud. And you may pay a monthly subscription fee to the cloud provider. In this virtual world, you can access your music or your books, or your whatever from any laptop or handheld device. That's the good news. But, will you actually own any of this "stuff" or will it all be able to disappear at any moment in a big "Poof?" Will most of the things in our lives be disposable and whimsical?  It makes you want to run to the cupboard and pull out that photo album, grab a book from the shelf, or open up a CD case and pull out the insert.

9.
PrivacyIf there ever was a concept that we can look back on nostalgically, it would be privacy. That's gone. It's been gone for a long time anyway. There are cameras on the street, in most of the buildings, and even built into your computer and cell phone. But you can be sure that 24/7, "They" know who you are and where you are, right down to the GPS coordinates, and the  Google Street View. If you buy something, your habit is put into a zillion profiles, and your ads will change to reflect those habits. "They" will try to get you to buy something else. Again and again.


All we will have left that can't be changed are "Memories".
And then probably Alzheimer's will take that away from you too!

Importance of sleep

Ranjan Das, CEO and MD of SAP Indian subcontinent died after a massive cardiac arrest in Mumbai. One of the youngest CEOs, he was just 42 year old.
 

What killed Ranjan Das and Lessons for Corporate India?
 
A few months ago, many of us heard about the sad demise of Ranjan Das from
Bandra, Mumbai. He was very active in sports, was a fitness freak and a
marathon runner. It was common to see him run on Bandra's Carter Road .
Just after Diwali, on 21st Oct, he returned home from his gym after a workout, 
collapsed with a massive heart attack and died. It was certainly a wake-up call for corporate India. 
However, it was even more disastrous for runners amongst us. Since Ranjan was an avid 
marathoner ( in Feb 09, he ran Chennai Marathon at the same time some of us were running Pondicherry Marathon 180 km away ),
the question came as to why an exceptionally active, athletic person succumb to heart attack at 42years of age. 
Was it the stress?

While Ranjan had mentioned that he faced a lot of stress, that is a common element in most of our lives. 
We used to think that by being fit, one can conquer the bad effectsof stress. 
The Real Reason:
However, everyone missed out a small line in the reports that Ranjan used to make do with 4-5 hours of sleep. 
This is an earlier interview of Ranjan on NDTV in the program. 
Well-known cardiologist on the subject of 'Heart Disease caused by Lack of
Sleep' have distilled the key points below in the hope it will save some of our lives.

Some Excerpts:

1. Short sleep duration ( <5 or 5-6 hours ) increased risk for high BP by
350% to 500% compared to those who slept longer than 6 hours per night.
2. Young people ( 25-49 years of age ) are twice as likely to get high BP
if they sleep less.
3 Individuals who slept less than 5 hours a night had a 3-fold increased
risk of heart attacks.
4 Complete and partial lack of sleep increased the blood concentrations of
High sensitivity C-Reactive Protein (hs-cRP), the strongest predictor of heart attacks. Even
after getting adequate sleep later, the levels stayed high!!
5. Just one night of sleep loss increases very toxic substances in body
such as Interleukin-6 (IL! -6), Tumour Necrosis Factor-Alpha (TNF-alpha) and C-reactive protein (cRP).
They increase risks of many medical conditions, including cancer, arthritis and heart disease.
6. Sleeping for <=5 hoursper night leads to 39% increase in heart disease.
Sleeping for <=6 hoursper night leads to 18% increase in heart disease.

Ideal Sleep

In brief, sleep is composed of two stages: REM ( Rapid Eye Movement ) and non-REM. 
The former helps in mental consolidation while the latter helps in physical repair and
rebuilding. During the night, you alternate between REM and non-REM stages 4-5 times.
The earlier part of sleep is mostly non-REM. During that period, your pituitary gland releases 
growth hormones that repair your body. The latter part of sleep is more and more REM type. 

For us to be mentally alert during the day, the latter part of sleep is
more important. No wonder when you wake up with an alarm clock after 5-6 hours of sleep, 
you are mentally irritable throughout the day (lack of REM sleep). And if you have slept for less than
5 hours, your body is in a complete physical mess ( lack of non-REM sleep ), you are tired
throughout the day, moving like a zombie and your immunity is way down.
Finally, as long-distance runners, you need an hour of extra sleep to repair the running related damage.
In conclusion:
Barring stress control, Ranjan Das did everything right: eating proper
food, exercising ( marathoning! ), maintaining proper weight. But he missed getting proper and
adequate sleep, minimum 7 hours. In our opinion, that killed him.
If you are not getting enough sleep ( 7 hours ), you are playing with fire, even if you have low stress.
Unfortunately, Ranjan Das is not alone when it comes to missing sleep. Many
of us are doing exactly the same, perhaps out of ignorance.
