Wow you are hardcore! 😎
How cold does it get in NZ? I noticed you used a pic of a dog sledder. The people of the arctic are indeed adapted to colder temps. I was in the high arctic one summer and the locals were walking around complaining about how hot it was and how they couldn't stand it. It was 12 Celsius! 😂

On the other hand, the same people, when they lived on the Land, wore seal skin clothes. Those are very warm. They lived in tents in summer, but igloos in winter. They also made houses from sod. The inside of their winter homes were warm enough to survive the extreme weather. Yet, life was hard, food was scarce, and people died young.

There needs to be a balance.
