Ever heard of “paper cuts” leaving scars? They can, but only if you pick at them. Please stop picking. One woman had a paper cut scar on her finger for 20 years—from a magazine. She framed the magazine. Legends say she still shows it at parties.
Another oddity: piercing scars. Those tiny holes on your earlobes? They can close up, but the tissue is changed forever. If you stretch a piercing too fast, you get a “cat butt” scar—a puckered, wrinkly mess that looks exactly like what it sounds like. Never Google that before lunch.
