Some people would pay for that.
One reason might be that I work with waste water and being often exposed to these kind of pathogens could help to keep good immunity against those bugs. If I get some splashes to face etc, it usually just leads not more than few extra s(h)itting sessions in toilet. But on the other hand, I never have had much of these bugs. Last time I got vomit disease 3 years ago from work trip to Russia. (Visited local waste water plant and ate salad in restaurant.. both could have been the reason)
