Answer
When a heavy load is placed on the back, the center of gravity of the body shifts backward. To prevent falling backward and to keep the body’s center of gravity above the feet (the base of support), a person bends forward. This forward bending compensates for the backward shift, allowing the person to remain stable and balanced while carrying the load.
