the theory is that our immune system is so primed to attack infection, that, lacking what was a normal barrage of infectious enemies to attack, the immune system becomes hyper sensitive, and over reacts, or even begins attacking the bodies own cellsSo, at a certain age, should we all be exposed to a low-level variety of infectious agents in order to give our immune system a good workout, on a similar principle to the flu shot?
So, at a certain age, should we all be exposed to a low-level variety of infectious agents in order to give our immune system a good workout, on a similar principle to the flu shot? More like, we should have constant exposure to low levels of infectious agents, like the more primitive people do. That, and have a few parasites (lower the blood iron levels). AND, eat less food.. We were designed for a much harsher existence.
