Don't know about everyone.
I myself have been in the Mile High City (so called because it 5280 feet in altitude), and in Colorado springs without ill effect, and I am from near sea level Washington DC.
When I was a kid we even drove the highway to the top of Pike's Peak, and played in the snow in mid July, at 14,000 feet with no ill effects.
Years later I spent half of week in Mexico City (a mile-and-a-half high) which is not only much higher than Denver, but is located in a bowl that collects the smog. And I had no effects. But I ran into an American lady with her two grown sons in the famous Anthropology museum, and one of the sons was really suffering and spacey from the high altitude. So everyone is different.
Love Pike's Peak! Was there when I was a kid then I took my kids up there
