The
answers are not easy because:
§There are many theories
regarding the causes of aging,
each plausible in its own domain, each with its own group of proponents, and each based on credible research evidence.
§These theories are like the blind men of fable who feel only different parts of an
elephant. That is, each aging theory is valid in its
own right but
presents only a small part of the picture.
§A larger unified theory of aging is only now starting to emerge.
