A person can live without food for about a month, but only about a week without water. If the amount of water in your body is reduced by just 1%, you’ll feel thirsty. If it’s reduced by 10%, you’ll die.

There is a snake, called the boomslang, whose venom causes you to bleed out from every orifice on your body. You may even turn blue from internal bleeding, and it can take up to 5 days to die from the bleeding.
