From TFA: > To see this, we can look at our own immune systems. For instance, immune cells inside your body known as neutrophils are just as suicidal as the worker bees. When bacteria invade your body, neutrophils migrate to the site of infection, unleash a whole cocktail of toxins onto the bacteria, and then proceed to die within 1-2 days. In both cases, the suicidal nature of neutrophils and that of worker bees benefit the bigger entity that surrounds them. For worker bees, their death may save the colony from Winnie the Pooh, and the death of Neutrophils may save you from dying from a bacterial infection.
