Try breathing above a mere 20,000 feet but don't overdo it.
I also liked your comments about folk ledgends and stories and that travel was more limited. You are right but your mistakes are usually only by degree. So what.

I also wonder if climate change will one day reduce the amount of viable breathable air. I don't know but with enough fires, ocean die off of diatomic fauna and flora and forest defoliation, there has to be an emergence of a lower concentration of oxygen.

Today suffocation is not a popular recognized outcome of climate change.
There was an ancient time in Earth history when the planet did not have an oxygenated atmosphere. In fact oxygen was a poison for the life forms that existed back then. Cyano bacteria was the culprit that releaased O back then.
