So what?

Improving healthcare and medicine should be one of the core goals of civilization, so eventually we should have healthcare good enough to enable "practical immortality": No "aging" and no deaths save in extreme cases or physical accidents/violence.

In an ideal future, the majority of humans SHOULD be all over 100 years old! and hale and healthy as a 30 year old.

The problem is not "how long most people have been alive", maybe the problem is our unwillingness to reassess social assumptions established >2000 years ago:

That everyone has to "work", everyone has to "earn", everyone has to constantly "buy", and that everyone has to constantly pump out babies so they can also keep doing the same...
