On Saturday, my mother turned 65. As is typical for 65-year-old women, she wanted to go sky diving. So we spent the weekend with her in a rented house on the beach south of Galveston. And she jumped out of a perfectly good airplane, as they say. Despite clouds and occasional rain, we spent quite a few hours on the beach, which felt great. Even after a couple of late nights, a little bit too much beer, and way too many cinnamon rolls, I feel quite recharged. Which got me wondering why beach time is so enjoyable.
