I just saw this article, and thought of the bunk beds we had for the boys when they were little, and the bunks we have at the cottage. I think it depends on how wild the kids are. It also says the dorm injuries are high, because college boys are idiots! I especially like the part that says the brain doesn't properly lay in risk/reward mechanisms until the age of 25.
Of course with all these things, you have to put in some perspective. If the kids are wild, are bunk beds the biggest threat? If the young males are idiots, do they get killed by bunk beds or motorcycles?
