If you could trade one bodily function with another person and still receive the same benefit what would it be? I would trade sleep because if I could reduce my hours in 1/2 how much more would I be able to accomplish! I would trade it for eating or even going to the bathroom because even at those times I can continue to think and read, especially if those hours were before everyone else got up. So if anyone can find a way to make this trade occur I’m all in.
