I'm curious whether you have any science to back that up, not having a crack at you, just curious?
I think the link with living at altitude is still a bit questionable.
Do non EA people born and raised at altitude share this "advantage"?
I have seen no evidence of that.
Therefore I'd be left thinking it would be an inherent trait. I would think that any reasonably sustained exposure to altitude would then develop it to the same degree.
Being in the womb, born and grown your first few years of life at high altitude would give you physiological advantages that you would never be able to change later. The heart grows bigger and stronger (per beat) the chest cavity grows larger, lungs bigger, yet body mass smaller.
Basically you have a big pair of lungs to suck in O2, a big strong heart to deliver it to the body per beat, and a smaller body to deliver it to. That equals more oxygen per cell.
Think of a suzuki rice rocket motorcycle vs. a 4 cyclinder SUV. The motorcycle blast out using less fuel and leaving the heavier SUV lugging behind in the dust.
This all happens in the first couple years of life and it's not something you can change at 10 years or 20 years if you were born at low elevation.
