Why there is short life span among Indians?

I feel the basic reason for shorter life of Mumbaikers and people living in metro cities of india may be due to the life style of living.  They live a mechanical life.  Most of the metro cities are filled with various kind of pollution to name few water, noise, air etc.  These pollution reduces the life span.  There fore we should learn and cultivate to lead hygienic life, grow lot of trees so that we get fresh air, live natural life. In fact the people live in metro don't have time to spend with their family's, attend get to gethers, social functions etc.  They have forgotton to enjoy the life, smile & laugh. That's why Laughters clubs are being formed.

I think the reason for most of the Indian population's faring poorly on the life expectancy parameter is because around most of the country's population lives in very unhygienic conditions like in slums. I think ignorance among citizens is one more reason. Tuberculosis, widely known as the poor man’s disease, also has a very high rate of infection mainly due to unhygienic living conditions; many spread it unwittingly without knowing that spitting is a common cause. Air, water and food in the city are contaminated thus is leading to increased morbidity among the citizens, thus affecting the life expectancy in the country.

The lifestyle of most of the Indians are very much unsystematic. Living life on the edge, scrambling for a toehold on trains, snaking one’s way through traffic snarls, fighting to find a roof over one’s head all combine to make most of the cities in the country never sleep. I think mental stress, lack of physical exercise and poor dietary habits are decreasing the average life expectancy of most of the Indians. This year’s Human Development Report on average Indian man reveals that maximum deaths in the country is caused by heart attacks followed by tuberculosis, cancer, kidney failure and HIV/AIDS and that such numbers are increasing every year — in 2006, around 12,606 died in Mumbai alone due to heart attacks against 2005 figure of 11,921. Around 9,490 deaths in the Mumbai alone in 2006 were due to TB against 8,836 TB deaths in 2005. In 2006, cancer and kidney failure led to 6,212 and 2,190 deaths respectively. Eating irregularly and eating junk food, lethargy, less sleep and long hours of commuting worsen the problem. People don’t even smile these days.
