a man who is suffering from a great illness or a great fear is automatically relieved of all other illnesses or anxieties. “Have you noticed,” he asked me, “that you cannot accumulate illnesses? Suppose you have a serious or incurable disease, a serious cancer or a good bout of TB, you will never catch plague or typhus; it’s impossible. Moreover, it goes further than that, because you never see a cancer victim die in a car accident.”
