The end of work + the end of aging ...

[Lanius]

1. Living longer is already creating problems, mainly because we've extended lifespan but

not health span - the length of time when a person is healthy and free of senescence. Now we have many folks living into their 80s and 90s but they're sick or disabled for 20-30 years, increasing health care costs and lowering quality of life.

If we were to eliminate aging and have an indefinite health span it would most certainly upend the social and economic orders. What would life be like it the rich never retired and the younger generations never had a chance to advance past a certain point in their careers? Also, what if you became paralyzed from the neck down and were ageless? Maybe medicine could heal you but not completely, and you'd live centuries with your disability.

Another question I have is: If humans don't age, then would we ever really grow up emotionally? Our personalities depend on our endocrine system and brain, both of which change as we age beyond our 20s. If humans end up being physically 20, 25 or 30 for centuries will they emotionally be "stuck" at that age?

However, no one will live forever; we'll still be susceptible to disease, poisons, violence, suicide and accidents. IIRC, some actuaries have predicted that -- based on the death rate of 25 year olds -- ageless people would live about 1,200 years, when they would die of some non-age-related event.
