According to this article, 200,000 kids are injured every year on the playground, and 15 die. I definitely romanticize some the past, but as with most things, it's probably mostly romantic.

In a lot of ways, I think the things outlined in the article, especially risk taking, are more mental than physical. You can be risk averse on that old metal gear and risk taking on the new plastic stuff.
But some of the descriptions, what fun is a slide that overheats? Who cares about the romantic notion that some kid might get burnt.
Some of that doesn’t even look fun, unlike the like giant wood labyrinths of the eighties, those I miss.
