Hmmmmmm . . . . . the mind wonders - did we have a book burning that I slept through in which all of this knowledge was lost??? As a kid growing up, we knew that there were good and bad germs but that, overall, germs help strengthen or develop the immune system.
One of the biggest complaints from doctors today is about anti-bacterial soaps and how they are preventing the body's immune system from developing antibodies against common germs. I notice that almost every small cut I get requires neosporin to fight the infection that invariably follows an untreated cut.
Use to be that when I got a minor cut, I could just put a bandage on it and go about my business. Not so today. I like the anti-bacterial soaps, but I agree that they are, ultimately, causing more harm than good by not allowing our immune systems to work properly.
i know that there are other examples, that just the biggest one that I have noticed.
When I was a kid my frequently abraded elbows and knees were regularly painted red with merthiolate. Come to think of it...whatever happened to merthiolate?
So our grandmas were right. Eat dirt!
