What better way to show that age is just a number than to run laps around people far younger than you? That's just what competitors in the annual Idaho Senior Games do. Athletes are all age 50 and older and compete in everything from tennis, bowling and racquetball to basketball, softball and track and field. They're out there breaking records while some of their grandchildren are sitting on their butts playing video games. Looks like they've still got a few important lessons to teach. And if you don't listen, watch out. They can catch you.
