It is true that a few studies have been made. Where all the inhabitants of a particular area enjoy exceptionally good or bad health, scientists have identified contributory factors such as the presence or absence of substances like iodine, fluoride, calcium. or iron in the water supply, or perhaps types of land that provide breeding places for pests like mosquitoes or rats. Moreover, we can all generalize about types of people we have met. Those living in countries with long dark winters are apt to be less talkative and less vivacious(活泼的) than inhabitants of countries where the climate is more equable(稳定的).And where the olive and the orange grow: the inhabitants are cheerful, talkative, and spontaneous.’ But these commonplace generalizations are inadequate: the influence of climate and geography should be studied in depth. Do all mountain dwellers live to a ripe old age? Doe the drinking of wine, rather than beer, result in a sunny and open temperament? Is the strength and height of one of the Kenyan tribes due to their habitual drinking of the blood of cows? We are not yet sure of the answers to such questions, bat let us hope that something of benefit to mankind may eventually result from such studies. 61. ________ might serve as a suitable title for this selection.
