Although possibly selfish, those would be interesting wishes. You could do all kinds of things you couldn't normally do in real life (like jumping off skyscrapers without a parachute and surviving), and you'd be able to read a lot of books...wait, would you still have to work full time (before you retired, but that would come way late since you'd have to save up extra money) to support yourself and your family? 'Cause that could really limit your reading time and I suspect it would be a long five hundred years...

Then again, eating would be unnecessary, as would a great many other things. So maybe it wouldn't be so bad after all and you could still retire at a reasonable age.
