"Way back in my misguided leftist days in San Francisco, I knew two families with wildly-varying child-raising philosophies. One couple had a lively little boy who ran barefoot in damp, chilly, meeting halls that exhibited the same standards of hygiene as many radicals did personally. He ate hot dogs, chips and candy, some picked up off dirty floors. He was bright and energetic and never sick.
Another couple had a little girl who was a hothouse flower. She was fed organic baby food and kept far far from other ragamuffin children and any adult with even a sniffle. As anyone who knows anything about immunity would guess, she was sick most of the time."[Power Line]
