Right, what I mean by "based on the lifespan of the people" would be more of a percentage… not the full expected average lifespan.
So, for example, it could be 80% of the average life expectancy in the U.S. which looks to be around 76, so that would put the cap around 61.
But perhaps we could base it on studies of cognitive decline instead. If some future medicine is discovered (that most people have access to) which would allow everyone to continue functioning well at an older age, then I don't have a problem if the average person is still doing well at an older age.
In this case we could use some percentage of the average age of cognitive decline instead.
