Just as a thought experiment, what would be wrong with extending the vigor of youth twenty years beyond our societally imposed retirement age, 65?
Two decades out from under the thumb of the expectations and institutions would seem a just reward for the labor of our elders. How many people work for the chance to travel the world, and then find themselves physically kept from doing so?
Absolutely nothing. But reward for labour is a Western notion. So yes for us living in Canada, USA, Western Europe...etc there would be absolutely wrong with living forever and rewarding ourselves for all our marvellous work with exotic travels until we're bored and then we can just take the "death" pill at a time of our own choosing.
In your retirement travels to distant lands, however, it is very likely that you would encounter people who do not view life in those terms. You might discover that they work simply to survive, and perhaps have some kids for whom they try to make life just marginally better. And maybe in 50-60 generations, the ancestors of those hard-working people would be able to enjoy themselves a little more and spend their 60s travelling the world just to see what other places look like. With an anti-ageing drug in the hands of rich westerners, it is very unlikely that that day would come.
