I believe in colder climates you have a larger percentage of a stronger society, more people who survive the cold, become acclimated, work with it and adjust their diet usually are stronger and liver longer. In other words a cooler climate weeds out the weaker. having lived in Alaska for the last 20 years I can see the differences in the culture against the people say from LA or Houston.

While that’s true, the reverse is also true. People acclimated to the hotter and more humid climes will thrive while those from the cold climes like Alaska, Canada, etc., will suffer a lot.
In early 1960s, my FIL (oldest of 9 kids) invited two of his brothers and their wives (they all lived in Racine WI) to visit us in the DFW area in July. We took them all over the area for several days. They thought they would die if not in the car or house with a/c.
When my daughter was less than a year old, the FIL took us on a drive up to Racine to show off his grandkid... in February! We were there for several days, with temps at -24F in the daytime! ....As a Native Born Texan, I spent a lot of time when we were indoors wearing my Navy peacoat and layers of clothes while sitting by the heating vents, while the locals sat around in light sweaters eating kringle and drinking coffee.
I enjoy reading your postings about happenings in Alaska.
I used to be an oil rig mechanic in the mid 80’s in NE Texas when it was near 100F with almost as high humidity, totoally friggin miserable, I basically reached the limit with only a 30 degree increase above the standard normal 72F working temps. Just cannot work much unless the humidity goes down, so I went west and worked in 127F temps in Vegas at less than 10% humidity, doable.
But I can work in -50 temps as long as I have the clothing, a much further temperature spread. I can and do work in the range of zero to freezing without a coat for short periods as I wear hi tech thermal underwear, conversely I cannot realistically wear anything to fight the heat, so going cold was the logical decision. Most people I run across just simply cannot acclimate to sub zero temps while I know I can adapt to real summer temps in a couple of days.
So in ending this discussion living in the cold isn’t for everyone, usually the weaker folks complain and quit. Such as how many come to Alaska and not even through the six month long winter bail out and leave.
