The Key To Longevity IS...

 Selecting The Right Parents

Exceptional longevity results from favourable genes much more than from a healthy lifestyle and environment, according to the first extensive genetic analysis of people who lived past the age of 100.

Researchers at Boston University have identified 150 genetic variants that, taken together, can predict exceptional longevity with 77 per cent accuracy. 

So basically, they say that making it to 80 is due to living a clean life, and past that, one's genetic programming is the most important factor in chugging towards another 20 years.

And for THAT they needed a "study". No breakthroughs, no how-to, no much of anything.

If you come from long lived folk chances are you'll be long lived too.
