The ageless politicians in India

In India, they just elected a 72 year old lady as their new President. She defeated an 84-year-old opposition candidate for a six-year term in the office! The longevity of politicians in India is truly remarkable Most of the Prime Ministers and Chief Ministers in that country hit their peak in their seventies! I wonder what is the secret for this phenomenon. It could be that in India, people consider older people to be wise and more cautious than the young. So age may never become an issue for a political office, unless the candidate is obviously senile. Also, I suspect that the older politicians in India are in better shape, as many have followed the austere eating habits of Mahatma Gandhi, and are used to walking a lot in grueling campaigns in their early years. Of course, the younger generation of politicians in India is different. They are used to the finer things in life. Most are overweight and out of shape, well on their way for a heart attack or stroke before reaching seventy!
