> If I could extend my life by 50 years of good health I might take that offer. If I had to extend it by 500 years, I'm pretty sure I'd decline. If I had to extend it 5000 years I'd certainly say no. 5M years of existence would be torture.

is this a thing you worry might happen? like, if life extension is developed, you're concerned it will come in the form of a 5 million year increment, take it or leave it, no possibility of suicide in the middle?

> When people express the desire to live forever, either here on earth or in an imagined afterlife, I wonder if they have really thought through the consequences.

i expect we'll manage to simply end aging first. that won't prevent you from walking out into rural alaska in your underwear.
