Teenagers go out of their way to do dangerous things. This is mostly anecdotal; I've been a teenager until pretty recently. But one thing I simply don't understand is the notion that safer playgrounds leads to a poorly calibrated sense of danger. What real life dangers truly appear in the playground? I haven't recently gotten a nosebleed from being hit on the nose with a rubber ball. What has mirrored the real world is all the diseases I've gotten.
