i always had a question about this:
if someone is bleeding and you want to help with putting pressure on the cut, we are always advised to use gloves, or worst case some kind of plastic bag in order not to get in contact directly with the blood. but why?
unless I myself have a cut in my hand, can i get contaminated by anything? can viruses etc... penetrate the small pores of my skin even if i don't have a visible cut?
