After studying case after case, he still found no possible cure. He had reached an impasse in his thinking. At this point, he changed his tactics. Instead of focusing on people who had smallpox, he switched his attention to people who did not have smallpox. It turned out that dairymaids apparently never got the disease. From the discovery that harmless cowpox gave protection against deadly smallpox came vaination and the end of smallpox as ascourge in the western world. We often reach an impasse in our thinking. We are looking at aproblem and trying to solve it and it seems there is a dead end. It is on these oasions that we bee tense, we feel pressured, overwhelmed, in astate of stress. We struggle vainly, fighting to solve the problem. dr. jenner, however, did something about this situation. he stopped fighting the problem and simply changed his point of view—from his patients to dairy maids. //edu. /picputer.
