75-100: Hopefully not dead.
Either it's a life worth living, or forced shutdown for me, while I still have a say.
You can't imagine being healthy at 75?
Most of my family members 75+ are still doing quite well.
My great grandma lived to 99 and wasn't particularly unhealthy until 98.
My mom's best friend's dad is 98 now, and was in pretty good health until 96.
None of them were poor and burdens on society.
My bleak answer is a refutation of the idea that merely "staying alive" is a goal. Staying physically alive is not enough.
