The other day Garry and I were watching a television show where the host was talking about grumpy old people.
He even had proof.
He said that infants laugh hundreds of times a day. (I'm not sure about that number -- maybe Molly is just a cranky young person) while people who were over age 50 only laughed 2-3 times a day.
I thought that the difference was kind of funny. I had to laugh. Which goes to show you how young I still am.
