My sister who is 80 complains all the time about having to do the maintenance tasks like feeding herself or taking care of brushing teeth and maintaining her hair. People with that attitude would kill themselves rather than live a thousand years.
I’m 70 and every step is painful. Other than that, I have no complaints. If I thought I had another fifty productive years, pain free years, I’d learn some new skills and start another business. I look forward to every day and I love cooking, eating and mundane tasks don’t bother me. But a thousand years? I think some people improve the world when they die. I’ve had a few bosses that if I still worked under them, I’d have killed myself. Politicians of almost any ilk already hang onto power WAY too long. If they were once perfect for the job, they eventually get stale and resistant to change. (I think Nancy Pelosi and Joe Biden have been hollowed out and someone is wearing their skin and animating them.)
Perhaps if we lived to be even two hundred, there would be laws forcing people out of their jobs, or power, after a period. If not, the entire society would ossify.
Years ago I read several books in “The Interview with a Vampire” series.
One of the things that some of the really old vampires had an issue with was that they found it hard to live in the world once they became over 500 years old. All their friends and relatives had all died hundreds of years prior. So, they felt out of time. Therefore, they would commit suicide. Like walk out into the sun and burn to death because they just did not want to live anymore.
It was of course a work of fiction.
