Ingesting all that crud over the years makes a man healthy. You build up immunities from that stuff. This is why so many kids today, the ones that are protected and coddled... get sick from the slightest thing....Allergies to peanuts and other simple **** was never an issue in the 60s as far as I knew.
You got a point there...now to think of it, I've often wondered about all of the different things that have been making people sick these days...things I don't remember when I was growing up.
