This is the second piece I read about how our prejudice against and paranoia about bugs and bacteria is costing us unnecessary illnesses. There is research going on at UBC as well in the same vein as this article, re strengthening immunity. I just read this article and again feel ok about my occasional desire to lick anus and even plunge my tongue inwards, mainly for the squeals of delight it can elicit. The caveat being the health of the recipient of course, but it can promote good health and robust resistance to killer bugs.
