There were lots that lived longer. You have plenty of mountain men that lived to riper old ages, and they lived rough. Most of my alleged male ancestors lived to older age.<quoted text>
They didn't live long.
Average lifespan maybe 35 or 45 years.
Cold weather is brutality. It goes beyond just a simple will to live to endure it. People die for the damndest reasons for this evolutionary "will to survive" to be such a driving force. Just look at those Russians and Germans in WWII living in sub-zero weather working with cold metal. Was easy to die, just sit still long enough in the cold and suffer a little pain, but something more than themselves kept them waking up the next day and going on. Yes, many died, but many more survived. Or were forced to beyond the physical level.
Many years ago I spent hours on a concrete floor in 5 degree weather under a car changing a clutch in a thin jacket. Just kept going. The cold starts shutting the brain down. You just keep going. Out in the frozen fields of Europe with death all around, a way of life, so to speak, and no end in sight, all you had to do was want to go to sleep, and it would all be over.
The individual is not as much in control of their destiny as they would like to think.
I have to sit here and cool my heels until late morning and it warms up enough to finish that damned thing.
