“Be not conformed to this world; but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect will of God.”
--Romans 12:2

I think it is Shakespeare who says, “It is the mind that makes the body rich,” and he might truly have added, “It is the mind that makes the body young.” We have known men and women who were positively old at fifty; that is, they were more decrepit in mind and body than many others whom we know who have reached their seventieth, and even their eightieth years. We used to think that this was due, largely, if not entirely, to physiological conditions; but in the light of the new psychology we are beginning to realize how very important a part the mental plays in the matter of premature old age, as in all other things. It seems too bad that just as a man has acquired enough wisdom to be of use to himself and others he should become suddenly smitten with a belief in old age, and thus nourish a thought that casts a cloud over his life.
