You will die in a week. You don't need food, water, sleep, TV, marmite or anything that you would die without (I would die without it). Now for the good news. For that week, you will have god like powers, being able to do anything (brainwashing, teleporting, making it rain bulbasaurs and putting nefs in uber). In that week, how would you change the world? The only thing you can't do is bring back the dead and edit time in any way. No buts.
