Dancing as exercise

From CNN:

Italian researchers have come up with a novel way for cardiac rehabilitation patients to exercise their damaged hearts without having to squeeze into spandex or gyrate in a gym: waltzing.

The dance proved to be just as effective as bicycle and treadmill training for improving exercise capacity in a study of 110 heart failure patients. Dancers also reported slightly more improvement in sleep, mood, and the ability to do hobbies, do housework and have sex than the others.

In other news, I finally appear to be rid of the nasty crud I have had recently that included a sinus infection and nasty sinus headaches. Damn, but that stuck around for a long time! And it also seems to have gotten more than just local friends. Stupid crud.
