Which needs based reward trait would you choose for yourself?

Argument could be made for "never hungry" since it would be most cost efficient but I enjoy delicious food and feel like the delight would be lost if I'd never feel hungry. It's quite satisfying to enjoy a good meal when you're hungry.
Never having to sleep could be pretty productive as well but I actually like sleeping and enjoy my sleepy evening/morning routines. Plus I feel like I'd get bored with my life if I couldn't shut my brain off for a while cuz there's not that many things I can do during those hours (except be gaming all night I guess).

Never having to use the bathroom though... that would make so many things so much simpler. Never having to face the stress of suddenly needing to use the bathroom and having none nearby or get grossed out because the only one available is some badly managed public one.
