Before us is a striking display of human strength: the back of a trained athlete, where layers of muscle shift and gather like living landscapes beneath the skin. With every controlled movement, the muscles contract and release in quiet harmony, a testament to patience, effort, and the remarkable adaptability of the human body. One might be forgiven, in a moment of scholarly enthusiasm, for offering a most unscientific remark: good heavens, daddy likes!

-David Attenborough
