>>76356472Your body is not a car, retard. Cars don't have self-repairing parts. Cartilage for example has issues with regeneration because there's no blood vessels there, it can only get nutrients through diffusion. Movement causes nutrient-containing fluids to be squeezed in and out of cartilage, which significantly increases the diffusion rate. More muscle mass can absorb stress that would otherwise go directly into cartilage and cause damage that the diffusion rate might eventually struggle to keep up with. It doesn't matter that movement also causes slight wear when it aids regeneration much more.
