美军特种部队一位学员这样说过:“当初教官在课堂上告诉我们哪些昆虫是可以吃的,而且我们将来一定会吃的时候,大家的反应都是‘我他妈的会吃才怪呢'。但当你一连在丛林里呆三天都找不到食物时,你的求生本能会使你无须命令而自动吞下任何东西,无论它是长脚的、土里钻的或者地上爬的,你都会毫不犹豫地把他们咽下去,否则你就无法活着完成任务,就会遭到淘汰。” A student of the U.S. Special Forces unit said: “When the instructors told us in the class which insects were edible, and when we would certainly eat in the future, everyone's reaction was that I would have fucked it But when you can not find food for three days in a jungle, your survival instinct will automatically swallow anything without command, whether it be long legs, earth-boring or climbing , You will not hesitate to swallow them, or you can not live to complete the task, it will be eliminated. ”
