Step on a land mind because I'd rather lose my legs than arms and chest, assuming i should survive. My feet don't have thumbs.......
Would you rather be a pro call of duty player, so much so (8+ hours a day) that you could support yourself this way, or would you rather do interesting things with your life and see the world at the risk of actually having to do work?
Close friend. Sorry, I would be selfish in that situation, and friends come and go.
Would you rather be trapped in a hot-air balloon for 3 days, or a space shuttle simulator for 3 days...both with thin oxygen, but just enough water to survive.
