during most of our evolutionary history, we got dirty, played in the dirt and lived with it surrounding us.

it's just common sense.

similar studies show that kids who grow up around farm animals, and pigs in specific, also get immune system benefits.givign

another example of common sense: in our state of nature, we occasionally bled.

now research has shown that giving a little blood periodically is healthy, especially for men (women naturally lose some blood every month). it helps, among other things, to lower the levels of heavy metals in the blood.

kids at play get occasional bumps and scrapes but in our sanitized society, those that don't play sports or play can go years without bleeding
