Two years ago NASA offered to send your name to the moon. Now they're willing to ! Sure, it's not a traditional freebie that comes in the mail, but I can't resist having my face float amongst aliens.
I fear it's the closest I'll ever come to traveling off our planet on account of my fear of heights. Plus, there's the fact that I'm vastly under qualified nor am I a rich Russian oligarch who can buy my way up there. But I'm sticking with the whole heights issue as my main obstacle.
