Utah also has some high, inhabitated elevations relative to this discussion. That are inhabited year round. (Mostly Ski Resort Personnel, caretakers) etc. Altitude sickness is a real thing, for sure. Usually over a short period of time most people seem to acclaimate. Shortness of breath on exertion, headaches, nausea, and fatigue are almost predictable.
The seasons seem about 3-4 weeks behind the lower elevations and the nights do get quite cool, the wind is a part of daily life. Weather changes in a heart beat. anyone living at that elevation without a purpose, outta seek counseling...
