There is a natural tendency for an accumulation of fat in middle age. Sedentary occupations, the intake of more food than necessary, defective elimination, a disturbed metabolism of the body and want of exercise—all these attendant consequences of middle age add stealthily to our weight by an unconscious deposit of fat in our tissues. Within normal limits this is allowable but an excessive deposit of fat is certainly detrimental to health. It soon proves itself to be a drag on the body and demands greater and greater muscular effort to move the latter.

It is a well-known, fact that our environments, faulty diet, indoor and sedentary occupations, unhygienic surroundings, the hurry and stress of modern life, our emotions and sorrows, all upset the proper functioning of our involuntary organs long before any other tissue in the body and affect the mind to make it lose its psychic balance.
