Eternal Life

I am sure one would shudder to think what would happen to this world, if human beings continue to live for ever and become immortals. I can't even visualise such a scenario . It will have far reaching familial,social and political impacts . Will governments offficially kill people who live beyond a certain age ? .Or will the life expectancy of a child determined at birth ? Don't for a moment thnik I am talking through my hat.The world famous futurist and life extension researcher Ray Kurzweil says that day is not far off.This is something akin to our Himalayan Yogi's (Like Baba - of the Rajini starrer) living for centuries.In his latest book 'Live Long enough to Live for ever' , he says this is possible and could be achieved in 2 decades time.Until now it is believed aging is a non reversible process due to degeneration and decay.He forsees tiny robots of the size of a blood cell called 'nanobots' injected in to our blood stream will keep us healthy and immortal . No doubt,world over,the life expectancy has been steadily progressing. This is attributed to better medical facilities and medical care. Already Japan has the highest number of centenarians in the world. It is quite astounding that by this month end Japan will have more than 36000 centenarians. This is an official report given by the Japanese government.Mind you , this has been achieved without Ray Kurzweil's nanobots !!!. What would happen all these Japanese centenarians have 'nanobots' injected in to their bodies?
