From Medium: A Q & A with Meghan Talarowski about why London playgrounds are more active and draw more adults than in the USA:

The playgrounds are much more open-ended. They also have riskier, more adventurous elements, like giant tree houses or huge slides. So they attract a much wider age-range. A lot of the playgrounds here are very small. You can’t get high up, which is something people like: giant swings, big spinners, tall slides. There’s a lot of physical stimulation in the environment there. I was seeing people 85 years old going down three-story tall slides. When Grandma is climbing three, four sets of stairs over and over again to go on these slides, you know there’s something special happening.
