Children nowadays, at least in the developed countries spend most time in from of the computer, iPad, TV, playstation and… everything digital. You can’t just see children playing on the backyard, spending time with other children, doing some sport (in except of playing football etc.).
When I was a child we didn’t have at least one computer in each house, TV was black & white, and playstation was something invited a little bit later.
I went out, called my friends, played using rubbers, ropes, knives (yes, knives), colored chalks or pretending to run a shop using plants and stones as products. We socialized, were fit and happy, didn’t kill (in games) for fun and collected stones instead of points for killed mosters. I liked it. And liked the idea of refreshing that games on St. Martin’s day. And what I observed was that children did have no idea about any of those games and weren’t strong enough to jump over the rope, especially in comparison to their parents.
