I'm born and raised in Norway, but I have to say that I wince whenever someone refers to us as "Vikings" in any capacity - it is almost exclusively a thing that foreigners/outsiders do, sans a small subculture of people here that enjoy Viking LARPING.

But, anyway:

When I grew up (30+ years ago) we did spend most of our time outside. Playing soccer, biking around, exploring the hillsides, building tree huts/house, playing along the shoreline, and so on.

If we were lucky, we would get an hour to play some NES/SNES/etc., but that was the exception. I especially remember our grandparents just sending us straight out, no mater what - they had a saying "Det finnes ikke dårlig vær, bare dårlige klær" which translates to "There's no bad weather, only bad clothing" - so we would be outside playing in all kinds of shitty weather. The "bad weather" excuse has always been a faux pas thing here, which gets hammered down from early on.

Seeing strollers outside feels completely natural to me, that's just how things have always been.

I also lived in Finland and Sweden a couple of year growing up - same same, but different. 90% of my childhood memories consists of playing outside in rain, sleet, sunshine or snow.
