Jogi babu has written a very relevant story. everybody wants to live long without realizing that they themselves cannot really enjoy life as they grow much older and also they become a burden on the younger people who necessarily need to feed and support them.
There is a little known genetic reason too. gene mutation to incorporate better qualities and capabilities can only happen if more and more new births take place. if people live to be 200 years on an average, then the mutations will be that much less frequent and human development will be that much slower.
