I can’t think of any scenario where living that long would be desirable. Think of the trouble one would have fitting with contemporary society over the centuries. It’s tough enough to deal with some of the nonsense in the past decade that is threatening to become the societal norm. 50 years from now, I’d be totally lost. 500 years from now? Unthinkable.
Being a geologist, I’d take it in a heartbeat. Would be a bit tough on you and whichever gal you hitched up with every 50 or so years though...
You’d watch multiple nations, empires, and whole civilisations rise and fall.
Imagine what I have to go through! I was born in the stone-age, son of Og, son of Ooga. This magic box all of you live in still fills me with fear, and what irks me the most is that not all of you agree with all the things I say.
