at when I visited the hospital, and the answers to the questions that the people cave me, the incidence of hypertension is probably over twenty-five per cent end might be in the olcer people as high as forty per cent. For seme years now general medical opinion indicate that hypertension is a stress diseese. It can be induced in animals by crowding. If one takes experimental animals of small size, -- rodents, for example, -- and puts into large cages where they ere free to move about, ls no particular increase in hypertension. them there If one puts them in small cages where they are crowded a good deal, and particularly puts them in positions where, because of inadequate space or, inedequate food, competition between them for sustenance and living space developes, then the incidence of experimental hypertension increases very greatly. It has increased in western peoples in time of stress. A study in Texas City in our own nation some fifteen years ago found that when a ship blew up in the harbor, the ship carrying ammonium nitrate, and much of the seaward portion of the city was destroyed, the inciGence of hypertension in the town rose greatly. It has been found also that when people with no particular ethnic hypertension are moved to areas of substantial stress in which they have to accommodate to new problems, hypertension emerges aes a disease. For exemple, Easter Islanders, an island off the coast of Chile, have no hypertension when they remain in their ethnic niche. travel there, When these men to Chile and enter the ccempetitive economic world they develope the same ermount_of hypertension as do the Chileans. In developed societies breaking of social patterns by individuals or by croups does lead to hypertension. Captain James Graham some forty years ago found that the soldiers of the British Fifth Army after defeating with Rommel's forces in North Africa developed a substantial frequency of hypertension which could not be alwavs relieved by simple rest. Even after keeping the soldiers in a rest zone for months, some of them left with fixed hypertension which they did not have before the start of this battle. Consequently I believe that the high incidence of hypertension is in part @ue to the cultural upheaval that has been induced in these islands by the results, direct or indirect, of the atomic bombs. There very likely are other forces here that have induced
