I spend a lot of time on planes and often observe people as they laugh at the sitcoms or whatever on the plane videos. I sat next to a guy yesterday who really belly laughed at the mindlessness that was on the screen. (He got me laughing as well!) We had a short conversation coming in to land and on the way to get our bags. He told me he didn’t laugh very often. I told him I laugh often, usually at the little things that happen every day, and at myself. How often are you laughing?
