I have been reading up on some kinesiology. I found this paragraph that clearly illustrates a deep area of what we should be studying. How do we stand and why do we fall over?
"To stand, walk, or climb without falling, we must maintain our center of mass over and within a base area. When someone is standing erect, the base can be considered the normal footprint. The shape, size, and position of the base changes depending on the pattern of movement and the activity. When walking, we constantly readjust our body segments over our base to maintain stability. The brain, vision, body condition, and the nature of the contact with the surface all contribute to the sensitive balance required to maintain walking stability. If a foot slips or is mispositioned, the center of gravity shifts outside the base area. When this happens, we shift our body parts in an attempt to regain equilibrium. If the center of mass cannot be shifted back over the base area, we fall."
