Went to the dentist today. They think I was born without wisdom teeth, but aren't sure. They'd need more x-rays of the back of my jaw to see if there are any extra teeth hanging around. Usually after the cleaning the real dentist comes in for a second to say hi, and today I was going to ask him why humans have lips. I've been thinking about this a lot lately. Many mammals don't have lips, and we had them back in pre-talking monkey times. The dentist never came by so lips remain a mystery.
