I would put everything I own up on the market and invest in all the elements, rite? Then I put all that in a box and bury it somewhere secret and get the map tattoo'd to me, then I'd wander the world making sure nobody bothered it...
Then in when humanity...wait...I outlive HUMANITY? I LIVE FOR INFINITY OMG. Ok, so scratch dat..
I forgot Infinity was playing. I would live indulgently on Earth until the Sun exploded, and I would make sure to be out of the Sun's grasp when it implodes. I would then travel the Galaxies alone and saddened that I couldn't post on the BBS...but I'd have Alien families and lots of money :P
