I actually have dexterity for origami. I have several instructional books. Once you get accustomed to the different kinds of folds and everything it's not that difficult.
My house was being fumigated so I had to take everything off the walls, including the curtains. I'm sure the neighbors got their fair share of my bare ass.
I would totally go skydiving nude. I have no shame. Skiing takes some practice. I only get to go a couple of times a year when it snows so I lose practice by the next time I go. I am glad to hear ^^ Most people say it would hurt xD And it's like what if a bird crashes into you on the way down? Ahh ...
