These days not being able to sit still is considered a medical problem, when the truth is that it's just boys being boys. In fact, probably those who are bored more easily are engaged at the difficult to solve problems and games. When I was a kid, I was told my attention span was short and that I had ADD, but in truth it was that I was bored. Given a difficult programming problem, for example, such as learning Win32 for example, I could spend hours working on it because it became a puzzle. Kids that think creatively are probably easily bored by conventional attention getters. They like solving problems.
