Okay so I know this is likely very silly but here goes, my step dad was in England in the late 80's. I am not sure when but I think it was about 28 years ago, maybe 25 somewhere in that range. He has been in my life for 12 years now so this is really odd that I am just now worried about this but could I have been exposed by him? I ask because I am living with my mom again. This is embarrassing but I read an article that some scientist are afraid that one could be exposed by human fecal matter, blood etc. We share bathrooms and what not, so what are my chances of exposure? Am I being really out there again?
