The human musculoskeletal system is an organ system that gives humans the ability to move using their muscular and skeletal systems and provides form, support, stability, and movement to the body.
“The master in the art of living makes little distinction between his work and his play, his labor and his leisure, his mind and his body, his information and his recreation, his love and his religion. He hardly knows which is which. He simply pursues his vision of excellence at whatever he does, leaving others to decide whether he is working or playing. To him he's always doing both.”
James A. Michener
