how long can a person go without food or water?
Perhaps surprisingly, humans can subsist for some time without food. I depends on the fat content of the individual's body to begin with, but one to two months is not unheard of. At that point, the body is so weakened that the heart literally does not have the strength to continue beating.\n\nWater is much more essential. A human will thirst to death in as little as four days, though if they remain inactive throughout the period, it is possible to last as long as three weeks, at the extreme. Most people will perish in seven to ten days, however.
