I'd do it.
Wife and kids die, boohoo. Get some more you've got 400 years more to do it again.
You're conditioned to expect only 1 go at life in some quasi Christian hetro normality capitalistic dream.
You'd be world famous, probably worshipped as some deity. You could lecture 21st century history on board generational space ships or Babylon 5.
Move to mars. Total recall. You'd want for nothing fusion powered washing machines. So ez. Replicators. Tea earl grey hot. Think about it.
Sign me up. Pussies.
Deity not diety
Probably would need a diety after 300 years.
If you're worried about pensions then I don't think youre engaging in the freedom.
