This is so obviously wrong that I wonder if you are deliberately trolling. You can just look at wrinkling skin, decreased peak performance and all the other pieces of evidence that the regerative abilities of the body degrade after age 30-40. Or you can look at the thousands of papers in the areas of cellular senescence and its many consequences: DNA damage, lipofuscin accumulation, glycoxidation, lipid peroxidation of the inner mitochondrial membrane, atherosclerosis and probably dozens of other processes that translate to the "body wearing down".
