The reason is clear. An efficient but controlled assimilative system is the first requisite for long life, and the pure Cerebral does not have an efficient one. Moreover, he is prone to neglect what nutritive mechanism he does have, by irregular eating, by being too poor to afford wholesome foods, and by forgetting to eat at all.
Physical Assets
¶ By reason of his deficient physicality the Cerebral can not be said to possess any decided physical assets. But two tendencies which help decidedly to prolong life are under-eating and his refusal to dissipate.
It has been said many times by the best known experts that "more deaths are caused annually in America by over-eating than by any other two causes." Under-eating is a very necessary precaution but the Cerebral carries it too far.
The Cerebral, lacking a large alimentary system, is not tempted to overload his stomach or overtax his vital organs. And because he is a highly evolved type, possessing little of the instincts which are at the bottom of most dissipation, he is not addicted to late hours, wine, women or excitement.
Diseases He is Most Susceptible To
¶ Nervous diseases of all kinds most frequently afflict this type. His nervous system is supersensitive. It breaks down more easily and more completely than that of the more elemental types, just as a high-powered car is more easily wrecked than a truck.
Music He Likes
¶ "Highbrow" music is kept alive mostly by highbrows. While the other types cultivate a taste for grand opera or simulate it because it is supposedly proper, the Cerebral really enjoys it. In the top gallery at any good concert you will find many Cerebrals.
