When people ask me why I'm not going on some roller coaster that goes upside down and around and around at something like 200 miles per hour, I don't want to just tell them I'm chicken. So, I tell them I'm not tall enough. You know that picture they have of a little person? They have them at the entrance to rides that are a little more challenging. You're supposed to stand next to it, and if you're not as big as that person that they've drawn, you're not allowed on that ride. I've got grandsons, on the other hand, who would love to get on some of those rides. They don't have the wisdom of my years. They don't have the well-developed survival instincts that I have, but for a long time they weren't allowed on the ride. They just didn't measure up.
