I thank you all for your responds in advance - to this scenario... few days ago me and my son went to play ice-hockey together. other adult player felt down on ice and broke his nose (actually a friend of mine who is quite promiscuous i have to say, so this is why i am thinking about it over and over). the nose bled quite a lot, leaving blood on bench and ice, the doctor helped him and so i dont think i did directly touch him, but i and my son - we were standing right besides him. only later i found smears of blood, one on my shirt and one on my son's shirt. not large. also we played for some more time so skated through the blood too (i didnt think about it that time as nobody else did bother...). only later i noticed he left stains on doorknob and also i borrowed him my shirt and i found it in my bag and this shirt certainly was stained with blood (i dont know how much - the tricky thing is, i gave him my red shirt, so the red blood cant be seen on it, but he had it on while he felt down, so there certainly was blood). all these things might be ok, as we skated a while more, so the blood on shirt in my bag, on doorknob etc would be on air for some time. but it is cold at the stadium and i dont know how long the hiv in blood would stay active, and when i think about the "chances" to catch something while rethinking it, they grow bigger and bigger in my head. especially when i think about those things you do and dont even notice like touching eyes, picking nose, little scratches on skin... (yes then the blood would go first on my hand, then to eye etc, so again, some tiny seconds on air...) please what do you think about this situation? i am the only one who bothers, so maybe i am really only overreacting, but some advice would calm me down. thank you very very much!
