What if you fell into a pool of lampreys?
With around 5 L (1.3 gal) of blood in your body, you’d manage to survive if only a few attach themselves to you. But in this nearly inescapable hell pool, there would be hundreds of lampreys. If 90 of them latched onto you for 24 hours, you’d lose enough blood to die.
