I used to think that one day, maybe in our lifetime medical science would come up with a way to greatly prolong our lives. Lately I've been reading a book that completely destroyed that notion. It will never happen.
What book is that? They do think the new generation will live to 120 or so.
The Third Chimpanzee. It had a chapter discussing how aging is caused not by one thing wearing out but many different things that wear out at roughly the same time (since having a heart that lasts for 500 years would be of no use if the rest of the body can only last for 120 years).
True that people will live for 120 years. At least
one person has already done so and it's entirely possible that a lot of people (mostly women) will do so in the near future. That would be more people living to the maximum range rather than extending the range.
But better medicine and safer living conditions won't help us live past 120 years anymore than better medicine and safer living conditions will help a mouse live past 2 years. In the wild a mouse might live for 2 years or it might be eaten by a hawk after 2 months. In captivity a mouse has a pretty good chance of living to the end of its maximum lifespan. No amount of medicine can help mice or men live beyond their maximum range of 2 and 120 years respectively.
