Why do our voices age and how? (Why do old people sound different than say a 40 year old, etc)

Speech/Lang student here! As you grow from a child to an adult, you vocal folds lengthen and strengthen (hence why your vocal range is larger and deeper than that of a child). But as you grow old, your vocal folds weaken. Vocal folds are like any other muscle in your body, they get stronger until a certain age and then weaken in old age.
