Athletic!
(Because i'm lamenting hugely over the flare up of knee and joint pain and fibromyalgia that's getting in the way of getting into the shape i've always dreamed of).
WYR:
Be able to explore at will, with ease and with no special equipment, the depths of all the oceans and seas or outer space?
Would you rather: Be able to transport yourself into any fantasy world you can imagine (eg. from a book or movie) or change your real life on earth exactly how you want it to be?
