They deserve nothing at all. I feel that the best way to deal with the blood issue is to not have it come up. This means safety first. Carrying a bright umbrella in rain (especially with poor visibility) instead of the approved drab one might stop you from getting hit in the first place, and then you won't go to the hospital at all. Using common sense and not going out in field circus when it is too dangerous might prevent an accident. Allowing people to exercise sensibly instead of denigrating it would allow people to get in shape, avoiding heart problems (and so would being less tight with time, so people don't need to eat at McDonald's every day).
Yet, they are so insistent on their rules that incidents happen that should have been prevented. Instead of returning safely home, they fight to refuse blood. They never ballyhoo anyone that is sensible enough to stay home in dangerous conditions instead of going to the boasting session, and then avoid a trip to the hospital that forces them to miss 10 or 15. Better for them if people suffer needlessly, get into needless fights, and waste so much time in the hospital than to have people not get hurt at all.
