I live in a high altitude area. It gets very hot. People will say that it's because we're "closer to the sun" as if the ~6000ft/~1800m difference is what matters vs the 93,000,000mi/150,000,000km distance to the sun is affected by something so small.
The difference is the lack of atmosphere to soften the various types of light from the sun.
I'm not a gastroenterologist, but I do believe when you have an o-ring issue you specifically do shit your pants.
