Experiment 1. Can you stand up without leaning foward?Harder than it seems!! When you are standing your centre of gravity is over your feet. When you sit down or are bending forward your centre of gravity is over the chair. To stand up you must move to get your centre of gravity over your feet but it is impossible to stand up if you don't lean forwards. When I tried it I nearly got it. But I nearly fell back any time I was pushing up because the chair kept on moving back!
