I HATE to vacuum!!!
With good reason!

I was a study participant at the local medical school a few years ago. The study was started by cardiologists (who apparently all have cleaning ladies and don't vacuum themselves) who kept hearing from their patients that they got really tired when they vacuumed. We strapped on this mask thing with a backpack that recorded how much oxygen we consumed when vacuuming using a variety of different vacuum cleaners. They recorded our heart rates, blood pressure before and after, etc.

The study results found that vacuuming was hard work. Suprise!

When I look at people doing tai chai (sp) it looks like the same kind of effort and physical control as vacuuming.
