You are the first generation to be completely consumed by not only environmental toxins (in the air, in your water, in your food) and completely immersed in EMF (cough*pulsating microwaves*cough). Now couple that with the fact that your feet rarely touch the earth (grounding) and you are rarely exposed to bacteria in dirt.
I think I can owe my relatively good health to the fact I played outside a lot as a kid, I used to actually walk around barefoot a lot, too, my feet developed big-time callouses, so after awhile walking around barefoot was nothing.
