Calories burned..hmm

According to this..

My job which is a YMCA Group leader with the prime time programs consumes...300-400 calories. Belly dancing can burn 250-300 calories. Housework consumes 150-200. Sex consumes 200-400. Interesting because I should be doing all those everyday. Hmm.

I think I should invest in a jump rope. It can burn 400 calories.
