Your immune system is basically that general who's perfectly fine with 40% casualties as long as the battle is won. When pathogens invade, your body cranks up the thermostat to a scorching 40°C (104°F) because bacteria fold like cheap lawn chairs at that temperature. Meanwhile, your own cells are sending panicked memos to management: "We're literally cooking in here!" But your immune system just shrugs and says, "Some of you may die, but it's a sacrifice I'm willing to make." The ultimate pyrrhic victory—burn the village to save it. Evolution's solution to infection? Just set everything on fire and sort out the survivors later.
