Gravity is a mystical force. You cant fight it. If it takes a hold of you might as well give in and go along for the ride. ^^like the guy in that video!
If I were a cop I'd get a pool going with the other cops to see who could get a drunk guy on the ground the fastest without touching the drunk. The heavy tape measure is a good idea, as well as touching your toes, and keeping your chin on your chest while walking the line. ;D >
