QuestionHow does the body and brain deplete as a person enters middle and old age, as compared to the brain and body of a fully developed, but young, person?
AnswerJoanna,
Not sure what you mean by "deplete". That is probably a very complex and expansive explanation that covers many branches of medicine... neuro, endocrine, nutrition, etc. But you may find some answers to questions on subjects I have written on my blog. Peruse it to see if that is helpful or you can submit another questions which is more narrow in scope and more specific.
