A basketball team...for grandma?

The latest craze for senior women's fitness may not be what you think. It's not yoga, hiking, or even strength training -- it's basketball. Dozens of basketball leagues for women over 50 are starting up all over the U.S., and it's thought to be part of a larger general movement by older Americans towards organized sports.

Of course there are some health risks associated with playing sports, for older players especially. Cardiovascular complications, arthritis, and knee injuries are so common many of the leagues require a doctor's approval before women can join.

But that's not stopping anybody. About 500 women from 47 states participated in the 2005 National Senior Games, and the trend seems to be getting bigger everyday. I think I can see why -- with team names like "The Hot Pink Grannies" it sounds like fun bunch of ladies!
