The Influence of Geographical Environment on Man A subject which seems to have been insufficientlystudied by doctors and psychologists is the influence of geography and climate on the psychological and physical health of mankind.There seems no doubt that the general character of the landscape, the relative length of day and night, and the climate must all play a big part in determining what kind of people we are. 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 than inhabitants of countries where the climate is more equable. And where the olive and the orange grow, there the inhabitants are cheerful, talkative, and spontaneous. We are not yet sure of the answers to such .questions, but let us hope that something of benefit to mankind may eventually result from such studies.
