An article on MSNBC.com says some scientists no longer see a limit to how long a human being can live. One scientist at a recent meeting of Oxford scientists even said the first person to live to 1,000 has already been born.
"Life expectancy is going to grow significantly, and current policies are going to be proven totally inadequate," he predicted.
Just how far and fast life expectancy will increase is open to debate, but the direction and the accelerating trend is clear.
Richard Miller of the Michigan University Medical School said tests on mice and rats - genetically very similar to humans - showed life span could be extended by 40 percent, simply by limiting calorie consumption.
Translated into humans, that would mean average life expectancy in rich countries rising from near 80 to 112 years, with many individuals living a lot longer.
Aubrey de Grey, a biomedical gerontologist from Cambridge University, goes much further. He believes the first person to live to 1,000 has already been born and told the meeting that periodic repairs to the body using stem cells, gene therapy and other techniques could eventually stop the aging process entirely.

I'm afraid I'm of the "believe no future, however rosy" school when it comes to rogue "scientists" making these kind of completely unsubstantiated claims.
I mean obviously obviously a human being is going to live longer with higher living standards and better health education and eating habits.
But it's a pretty big leap of imagination as well as faith from there to project a future of stem cell implants and gene therapy that allow someone to live to 1000 when that particular bio research hasn't even begun trials on animals.
Sounds to me like this guy De Grey just wants to make some headlines for himself, to further his own career, I could be mistaken, naturally.
The ageing process can be slowed down but never stopped altogether because what causes the body to age is not only material wear & tear, it's mental material pre-programmed at time of birth. That's why a 60 year old woman with worn out cells is about to give birth to a baby infant with brand new DNA.
Some yogis in India can live past 150 but only by slowing their metabolisms right down in trance meditation for 20 hrs per day and taking very little food. But they still have to die in the end. It's just that they are spending their mental "life savings" at a slower rate than the rest of us, that's all.
