The goal isn't a long life; it's compressed morbidity.The geneticist I mentioned above thinks that our lifespan is only 30% predetermined by our genes; whereas, our environment accounts for the other 70%. He cites the Okinawans as an example:
They are among the longest lived individuals only when they stay in Okinawa. Those that leave and live in Hawaii die much earlier.
Genetics and lifestyle come into play.
It's better to be lucky than good.
