I've never had a fear of my blood so much as an annoyance to it. Every time I get a nose bleed, it takes the best of 5 minutes to stop it and usually my sheets and pillows need to be washed AGAIN for the third time that week.
I saw a huge amount of my blood when I was being preped for surgury (enlarged lymphnode) and instead of feeling "Oh shit, is this nurse tring to kill me?" I felt "Damn, 5 vials of blood? Whatever, when can I get the surgury over with?"
Also, when I accidentally cut my palm with my swiss knife (the small one) tring to open a package, I got a shock but stayed calm and started to apply pressure to it with a wad of paper towels after I washed off the excess in my bathroom. Since then, I have always been careful when using my knife.
Other than that, I see blood from regulary popping pimples/black heads/white heads and get scratches from rough-housing with my sisters or just being "unbalanced" or "unlucky" that day.
