And yeah, assuming there is no after life (which is my assumption) I'd probably live forever just so I could experience lots of things. You could live in every different state or country for years at a time. It would be kind of fun. I guess you would do everything eventually, but you'd get to see changes in technology/culture/art.world leaders, etc. It would be interesting
