My grandma hit her brother over the head with a rusty shovel when she was 12, and as a result he went prematurely bald at 19.  She still admits that 63 years later, she doesn’t feel bad about it.

That, ladies and gentlemen, is the definition on “No regrets, just memories.”

wait, how did they know he went prematurely bald  because of being hit over the head?

Destroyed the hair follicles, he only went bald in one section of hair at first, but now it’s his whole head
