All of us have read thrilling stories in which the hero had only a limited and specified time to live. Sometimes it was as long as a year; sometimes as short as twenty-four hours. But always we were interested in discovering just how the doomed man chose to spend his last days or his last hours. I speak, of course, of free men who have a choice, not condemned criminals whose sphere of activities is strictly delimited. Such stories set us thinking, wondering what we should do under similar circumstances. What events, what experiences, what associations should we crowd into those last hours as mortal beings? What happiness should we find in reviewing the past, what regrets? Sometimes I have thought it would be an excellent rule to live each day as if we should die tomorrow. Such an attitude would emphasize sharply the values of life. We should live each day with a gentleness, a vigor, and a keenness of appreciation which are often lost when time stretches before us in the constant panorama of more days and months and years to come. There are those, of course, who would adopt the Epicurean motto of "Eat, drink, and be merry," but most people would be chastened by the certainty of impending death. In stories the doomed hero is usually saved at the last minute by some stroke of fortune, but almost always his sense of values is changed. he becomes more appreciative of the meaning of life and its permanent spiritual values. It ahs often been noted that those who live, or have lived, in the shadow of death bring a mellow sweetness to everything they do. 我们大家都读过一些令人激动的故事，这些故事里的主人公仅仅活在有限并且特定的时间内，有时长达一年，有时短到２４小时。但我们总是有兴趣发现，那命中注定要死的是那些有选择自由的人，而不是那些活动范围被严格限定了的判了刑的犯人。
