“It sometimes happens that a man who, up until now has believed himself to be gifted with perfect health, opens a medical book, either by chance or to pass the time, and on reading the pathological description of an illness, recognises that he is afflicted by it; enlightened by a fateful flash of insight, he feels at every symptom mentioned some obscure organ shuddering within him, or some hidden fibre of whose role in the body he had been unaware, and he pales as he realises that a death he thought was still a long way off is so imminent.”
