More to the point, why do we tend to die at about 75 yrs ancient? The body is self-repairing and should continue forever.
Olden books tell of people who died at the age of 500 years, or 453, or 766, and books to be written in the future will tell of people who died at similar ages (or much more), so what's going on?
I reckon it's simple, and it's something the so-called medical profession has overlooked. I call it "illness". Yes, people gett*en ill, and die, often at about 75 years ancient. It's time the doctors took my idea on board, and created cures for "illness". Then people like you and me (not necessarily the Prizemaster because he lives in a terribly unhealthy place where they actually eat disgusting snails and things), anyway people like you and me could then live to be 500, or 453, or 766, whatever you like really.
Women of course can't be allowed to live that long because they tend to go off. In fact many women deteriorate overnight - the one you wake with isn't always quite the same as the one you sha**** kissed goodnight the night before. But that's by the by, the important thing is to gett*en these doctors off their fat arses and ensure that I live long enough to see the United Kingdom win Eurovision.
The repairs are never as good as the original, causing gradual deterioration.
