Hemingway wrote a short story "A Day's Wait" in 1933, a nine-year old boy spent a whole day waiting for death because of misunderstanding the difference between Centigrade and Fahrenheit. "Glory under pressure", when facing the death, the little boy would rather stay calmly than do something uncontrollably. In his masterpiece "The Old Man and the Sea," an old fisherman, Santiago tried his best to catch a giant marlin, and then he fought with packs of sharks when he returned home, which almost exhausted all his strength. Whether in his short story or masterpiece, whether the little boy or the old man, when they faced the crisis, they showed the great courage. A man can be destroyed, but not be defeated.
