A roller blade's wheels are free rolling.. does that mean that you can stand on a moving treadmill and not fall on your ass??

remember, you are NOT HOLDING ON TO ANYTHING and NO ONE IS GRABBING YOUR ASS to keep you in place. You are in the OFF position, just like the plane. Just a big blob on wheels, on a treadmill... LOL
