@boomerang,
Oh, lab tech that I am still in my mind (way behind the curve but there in spirit), I was taught about antibiotic resistance from overuse, that back in '61 or '62.
I kept clean lab techniques, of course, but I'm the opposite in regular life, thinking some dirt is good for ya, antibody wise, and have since read that early exposure to cats and dogs is a good idea. I'm a one-person proof of that, having been kept away from them at early age. Achew!!!! Hardly met a cat in passing until I was in my twenties. Madly allergic to them after that. Was around a dog when I was seven - maybe that saved my doggie soul, since I can be allergic to them but not enough to keep me from having them as pets. Had my own first dog in my early thirties.
The whole clean your counters with antibacterials business has long driven me nuts, as well as the overprescribing of antibios, including in our food animals. Well, I'll just shut up now before I turn red faced.
I do agree antibiotics are sometimes a wise choice, and a clean house would be a good thing for someone highly immune depressed. I'm neutral on antibacterials in doctors' offices and hospitals, as in not sure what I think yet - but in those places, I just wash my hands.
Not quite shutting up yet - I'm generally pro vaccines.
