     "True, while humans self-repair, they eventually wear out (hopefully leaving their genes, books, or some other information behind - another discussion).  But the phenomenon of aging is misunderstood, largely fraught with mental biases and logical flaws.  We observe old people and see them age, so we associated aging with their loss of muscle mass, bone weakness, loss of mental  function, taste for Frank Sinatra music, and similar degenerative effects.  But these failures to self-repair come largely from maladjustment - either too few stressors or too little time for recovery between them..."
