Playground.

You can stick yer iPhones and Playstations up yer arse.

The kid that plays with a broken scooter, a tyre, some bricks and an iron bar will be the healthier for it.
I would spend days running through nettles in my shorts (corduroy shorts, if my memory serves.....they were all the rage in 1972); stepping on rusty nails; eating Texans; and generally being a tit to anyone who took any notice of me and it all helped build me into the rounded human being you now see before........

.....ok, I see your point.
