Why do humans do this?
Aliens from another planet go into a gym are puzzled as they watch humans running full speed on treadmills, and others, lifting heavy weights again and again. They wonder; “since no other creature in nature expends energy without a reason, why do humans do this? Does it get them “high”, or obtain them food, or sex?”
Us regular exercisers know the answer. Working out is therapy, both physical and mental. And the rewards we get are worth the effort.
Humans… let us not keep this a secret. Invite an alien in to your next workout.
