The power to never lose stamina or gain fatigue.
now that is what im talking about!its a great ability for daily things.what would you do with that power?be athlete or something?
Nah, I can't be bothered to be an athlete, though I will use it for being fit. And also watching anime at night without sleeping half way through an episode.
This is pretty close to what sweating is, which most animals can't do, giving humans a huge advantage.
