Hunger and cold will turn a man into a thief. If you're only taking in 800 calories a day, you're going to be in an unstable frame of mind. If your daily intake drops to 600 calories, you lose your sense of shame. At 400 per day, social order disintegrates.
飢寒起盜心，人們的卡路里若低到八百，就會呈現不安，若低到六百就沒有了廉恥，若低到四百，社會秩序就沒法維持。
