I was a medic in the army (not like in war or anything... The army here means that every man is trained in case someone (ahem, Russia) decides to attack) and it was quite nice. I hanged around the hospital most of the time and helped the doctors in some easy stuff. I never felt that it was impossible for me to get into that business because of the blood and stuff. I could easily distance myself from it and do what I was supposed to do.. but I never saw any serious cases while in there, just fixed a few broken bones and some cuts.
