After a discussion in class about the different theories of physical aging, you overhear some friends discussing their thoughts on why the body ages. One says he believes wear and tear theories are on to something. The other friend states that programmed theories of aging are likely the best explanation. You are not sure and think that both might be correct.Question(s):What does the wear and tear theory of aging believe about aging and what evidence is there to support this theory? What do programmed theories of aging believe about aging and what evidence is there to support programmed theories of aging? How could you integrate the theories together to explain the physical changes of aging?
