Dear 100 Hour Board,
how many calories do you burn when you laugh? I have heard so many different amounts for that one i'm not sure what is correct!

A: Dear Not sure,
It's hard to calculate exactly how many calories laughing burns because there are so many types of laughter. For example, I laugh a lot harder when my roommate throws water balloons at the couple making out outside our window than when my professor says another one of his corny puns. One hundred laughs are equal to the calories you burn while on a rowing machine for ten minutes or a stationary bike for fifteen. Using a calorie counter online, I determined that for my age and body weight that would be 150 calories. Go online and check it out for yourself. So every ten times you laugh, you burn 15 calories. And as long as my roommate keeps throwing water balloons, I'll be burning plenty of calories.
