If I had one day to feel no pain and be Indestructible I would do the following. I would take my chances and sky dive out of a plane. I was always afraid of falling, and would probably never try this because of all the things that would go wrong(I watch way to much TV). After sky diving, I would probably do things like ski, dive into a pool of a roof, do the cinnamon challenge, and other things I would never do because I am mortal. I'm sure there's more, but there's only so much you can do in one day.
