[Polyisoprene]

Sexier name for sure. We do still call the age before the current Nordic states were established the age of Vikings in Sweden.

The whole notion of Vikings being stupid and naive sounds very old fashioned. The whole idea that short seasons and snow would scare off any people from the Nordic countries is bullshit. Nuuk is at 64 degrees north, roughly similar to Reykjavík, Trondheim or the southern point of the northern third of Sweden. Which had been inhabited for much longer. The climate is slightly better in Scandinavia that far north, but Greenland would surely have been similar.
