Death at age forty and above, is usually due to the giving out of various vital parts of the body when subjected to strain. Nervous collapse, high blood pressure, hardening of the arteries, apoplexy, heart failure and kidney disease are some of the types of functional diseases that are likely to set in at this time.
To meet this period successfully, certain precautions need to be observed.
1) Cut down on the amount of food eaten sufficiently to combat the tendency to put on weight.
2) Be very moderate in the use of meats, salts and condiments; take plenty of water.
3) Get plenty of fresh air and exercise, but avoid strenuous exertions which overfatigue and place undue strain on the heart.
4) Take more recreation and rest.
5) Cultivate mental hygiene; avoid nervous strain.
Although the same nutritive essentials—fuel, protein, mineral salts and vitamins—are required to nourish the body from the cradle to the grave, it should be emphasized that the amounts needed are less in the latter part of life, especially after seventy, than in the more active adult years.
