You know some medical students did an analysis of different places where germ and viruses fester ie., bathrooms, public handrails, doorknobs and they also tested holy water ...holy water was the most germ filled place of them all....to be avoided at all costs.
I told this to R.Catholic once to make a point about traditions etc. , they were not impressed ....and I am sure they thought I was a heretic.
Maybe it is our resident troll.
