....and this is forever. It's not something that's temporal. In fact, from reading these words you have officially changed into your avatar/character, and have now gone into whichever world they belong to, and there's no way to escape.
Okay, since that's out of the way, would you enjoy it? How screwed would you be? Would you still look for a way out for the rest of your life?
Personally I'd love to be a Sangheili (Elite from Halo), because aliens are awesome, and being a human sucks. I'm not sure I'd want to be one for the rest of my life, but as I said, you don't have a choice. ;)
