ummm there are many people and I mean MANY people in India who are shorter than them and they have a lot of people who are quite tall by standards.
I lived amongst them for 2 years and played soccer with them ... and I YES you are right ... they had more oxygen available in their blood than me.
They literally ran circles around us for man to man and we would compensate with more of a passing game.
The biggest reason for their Oxygen levels being higher than people from low altitude levels was the size of their lungs.
This was a study done thanks to Ladakhis finally allowing some post mortem happening after joining the circle of Public Health Care.
On a man to man , child to child and budha to budha.
Their lungs out matched us at any age.
The surface area of their lungs was said to be larger from 8% to 24% sometimes but the 24 % is more extreme. Army doctors said it was usually around 8%. This allowed more and faster exchange of Oxygen, let me stop myself from going into the specifics.
However being at higher altitude and being pushed to task, also kick started a small growth in the lung size of folks from the lower altitudes, however this would recede when there was no exercise at higher altitude or the troops returned to areas at Lower Altitude.
The height thing was not a biological reality but a physical trick in 90% of the cases.
See what everyone observed that when ladakhis climbed height + carrying massive loads in a basket with a strap on.
1. The strap was never only on their shoulders, another strap or part of the strap was on their head or forehead. They wanted to keep their hands and shoulders free. Their spine picked up a lot of load. Bear with me as this leads into the next point.
2. The Ladakhis when going uphill tended to bring their (spine) parallel to the slope sometimes even more.
It almost seemed to look like they were about to kiss the ground when going uphill.
This bending down was what created the impression they were of short stature. They were just being bloody super effecient.
