Veer keodn Ji, that is very important observation. I am not sure, if it is correct to say that Amritdhari are less healthy. Because, to compare health quotients of two groups, we need to take many other factors as constant. But if the observation is correct, that is very much disturbing. Let us see, how being Amritdhari can affect one's health.
Positive Affects on Health:Vegetarianism benefits
No smoking benefit
No drugs/alcohol benefit
Early to bed and early to rise, makes a man healthy, wealthy and wise. (we know that)
Less eating and less sleep, may be positive for health.
Naam Simran-------- direct positive affect on health.
Physical Sewa is physical exercise----------good for health.
Sangat----------Positive affect through mental health
Dependence on Guru makes one confidant, thus physically healthy.
Negative Affects on Health:These affects could be related with our modern life style, being Amrtdhari.
Lack of Physical exercise: Spending more time/weekends/vacations on Kirtan/Katha/Computer instead of playgrounds/running tracks. There seems direct competition for time between Sangat and Playground, under present life style of Amritdhari Sikhs. Less interaction with non Amritdhari or Non sikhs, also keeps us away from play grounds/yoga sessions/gyms.
Attitude towards physical fitness: Worried too much about our spiritual heath, we pay less attention to our body fitness. Following our soul, we forget the body.
Food habits: More of milk fat is considered good in our Langars. Our Amritwela sessions are followed by unhealthy foods often.
More money power: Good habits, good education gives Amritdhari men and women, better jobs; which give less chance for physical exercise.
Conclusion:Negative affects are due to our personal weaknesses and not due to Amrit.
3HO people seem to be practical people, by giving more importance to health than holiness.
