Hello Again.
Sorry, this is my second question in less than one month. This might sound a little stupid of a question, but i've read so many things on the same topic and still can't get peace of mind.
While i was in China, i took the metro. Suddently i looked at my hand and saw blood on my second finger. It was a cut a little deep. I am a worried, there was too many people, and bad people happens to exist in this world, what if someone cut himself with something and cut me back in my hand directly, could that be an HIV risk? I had in my back pocket a map and a metro card, which both have sharp borders, maybe when i tried to get them i cut myself, i dont really know what happened, but bottom line i am worried, should i ??
