re: If you were truly immortal, how would you pass the time?

I would still go for something along these lines as well, but it would be harder if it started today. Being invincible/immortal means I could partake in high risk high payout operations like drug cartels without worry and with secrecy being of the utmost importance in that sort of buisiness I could stay relatively obscure. The biggest issue would be creating multiple prominent false identities to interact with the mainstream world. After I have that worked out I could use the money I gather to fund research projects for space flight and hopefully speed up the development of a hyperdrive so I don't have to wait so long for one to develop. Once we accomplish that, explore the universe and other alien civilizations and start working on becoming an interdimensional being.
