And look at those who don't make the trip, figuring (incorrectly) that the simple bandage would do the trick. Maybe they get lucky... and the injury "sort of" heals. Result, a body part that "sort of" works, but not at peak condition. Or perhaps an advanced surgical repair is needed to correct the original damage PLUS the damage done by not attending properly to the injury in the first place.
Now who's run up the insurance rates, hah?
