From the physical point of view, it can be expressed by potential energy. The higher the height, the greater the potential energy of an object, and the faster it will fall to the same plane, and the greater its function. After falling, the speed will be reduced to zero, and the kinetic energy will be zero, so the human body needs to bear these kinetic energy. The greater the kinetic energy, the greater the harm it will do to the human body.

therefore, the higher you stand, the more painful you fall.
