Gee, that's strange. You mean that you want your body to slowly descend into decrepitude, and your mind to slip?
What objection could you possibly have to people reaching the age of, say, thirty-five, and then remaining in that state of physical and mental fitness for, say, another four or five centuries (until - as statistics demand - they eventually suffer a catastrophic accident, like burning up on re-entry)?
Regards,
I’m on the fence on this. Let’s accept that it’s possible to do this. A few of the implications of lifespans reaching 300 to 400 years are:
1. For humans, destined to live 400 years, the simple act of crossing the street would be dangerous. Many people would avoid all that and much of every kind of activity. This would greatly reduce the quality of life in all cultures and leave countries open to invasion and plunder(sort of already happening).
2. Jobs and careers would be held by Elders for centuries. Newborns would would have huge problems at age 20 of finding any worthwhile work. (Also sort of happening now ).
—— good grief—— I guess we are there now!
3. Overpopulation would require colonizing new planets to acquire additional resources and space.
Asimov wrote some science fiction regarding the issues that would arise with increased life-spans. 5 novels called the Robot series. (Robot Dawn, Caves of Steel, etc). A great summer read.
