My kids and I were having a good laugh yesterday after watching a video on balance. One of the questions that was asked is "who has a lower center of gravity, boys or girls?" and supposedly the girls have a lower center of balance.
Well to prove it, they tell you to distance yourself three feet lengths from the wall, turn around, lean your head on the wall. While doing that, you lift a chair from underneath you, and then you try and stand straight up. The girls should be able to do this, but the boys shouldn't.
You have to try this. We were laughing so hard. We did prove its not a boy-girl thing, but its hilarious to watch.
