I'm a picker. It's hereditary. I pick my head, my skin, my ears.
the bug's head, ears, nose crustys
The Hub's skin
I think it's anxiety related. I especially noticed when I was in graduate school that while I was reading I would run my hand through my hair, fingers on scalp trying to find anything available to pick. It's weird I know. Not even sure if it's a habit or a disorder. Sorry to gross ya'll out.
