Yeah, that looks to me like an outdoor fitness installation, not a playground. Those aren't too hard to find, though, at least around where I live; most high schools or colleges of any size have one, and I've also seen a few near practice fields or parks popular with runners.
Back in the Seventies there was a fad for public fitness trails with a lot of the same equipment, which might do in a pinch. Those will be a lot more spread out, though, and a lot of them are in pretty bad shape four decades on.
Yeah, there is one of those trails (somewhat) near where I live! That was what I was thinking of when I saw the video.
Thus spake Eliezer:
It seems that many here might have outlandish ideas for ways of improving our lives. For instance, a recent post advocated installing really bright lights as a way to boost alertness and productivity. We should not adopt such hacks into our dogma until we're pretty sure they work; however, one way of knowing whether a crazy idea works is to try implementing it, and you may have more ideas than you're planning to implement.
So: please post all such lifehack ideas! Even if you haven't tried them, even if they seem unlikely to work. Post them separately, unless some other way would be more appropriate. If you've tried some idea and it hasn't worked, it would be useful to post that too.
