Many have boasted that they can take of what they call the good things of life to their full, without any bad effect, and looking over a few years, or even many years, it seems a fact. Some of us have known of such men, who have been esteemed for their joviality and good nature, who have suddenly broken down at what should have been a hearty middle life. On the other hand there are men who were badly equipped for the battle of life, with indifferent constitutions, who never had the buoyancy and overflow of animal spirits, but who with care have long outlived all their formerly more robust but careless companions. Simple versus Highly-flavoured Foods.--It is very difficult to decide to what extent condiments and flavourings should be used. These have stimulating properties, although differing from the more complex properties of alcohol and the alkaloids. The great differences in the dietetic practices of nations does not appear to be in conformity with any general rule. It varies with opportunity, climate and national temperament; though doubtless the national temperament is often due in part to the dietetic habits. Some races are content with the simplest foods, large numbers subsist chiefly on rice, others on the richer cereals, wheat, oatmeal, etc., and fruit. On the other hand there are races who enjoy stronger flavoured food, including such things as garlic, curry, pickles, pepper, strong cheese, meat extracts, rancid fats, dried and smoked fish, high game or still more decomposed flesh, offal and various disgusting things. The Greenlanders will eat with the keenest appetite, the half-frozen, half-putrid head and fins of the seal, after it has been preserved under the grass of summer. In Burmah and Sumatra a mess is made by pounding together prawns, shrimps, or any cheap fish; this is frequently allowed to become partially putrid. It is largely used as a condiment for mixing with their rice. Numerous examples of this sort could be given. There is scarcely anything that it is possible to eat, but has been consumed with relish by some tribe or other. The strongest flavoured, and to our minds most disgusting foods are eaten by the least intelligent and most brutal races. It is hunger that compels the poor African bushman to eat anything he can get, and the Hottentot not only the flesh, but the entrails of cattle which die naturally, and this last he has come to think exquisite when boiled in beast-blood. All this shows a wonderful range of adaptability in the human body, but it would not be right to say that all such food is equally wholesome. The most advanced and civilised races, especially the more delicately organised of them are the most fastidious, whilst it is the most brutal, that take the most rank and strongly flavoured foods. Even amongst the civilised there are great differences. The assimilative and nervous systems can be trained to tolerate injurious influences to a remarkable degree. A striking example is seen in the
