I agree and I also question... why do we need antibacterial soaps and lysol cleaning spray NOW? what about back in the day? they never had this crap...

in medieval times they never had to clean anything.. they never formally bathed but once a year, and even then it was recycled water, they crapped wherever they damn well pleased and look humans are still around

well then again they had the black plague but thats probably because their streets were paved in shit and they had dead rats floating everywhere...

But more recently... Indians (native americans) never really had to disinfect something and they turned out alright (until the pilgrims came but thats besides the point), whenever they got sick they used herbal remedies and stuff. And the population was stable.

well I figure anyway antibacterial soap is actually bad for you... it kills 99.99% of germs. Well what about that 00.01%? No they're not just lucky they're the strong ones. And now that the 99.99% percent are gone it leaves more room for the strong ones to multiply. And thats bad.
