ELI5: Why do I feel compelled to pick at a scab instead of letting the skin under it heal and have it fall off naturally?
gpt
I wouldn't say compelled, but maybe just out of boredom really. You don't spend your time picking a scab while you are on the field playing football, you do it while you are in the middle of a lecture in your Psych. class. You pick at it because it's something to do, and its something abnormal on your body to pick at.
