Another factor one should consider to explain this
correlation is that the lower air pressure at higher
elevations reduces the amount of oxygen available to
the body for use. Over time this would increase its
efficiency at respiration. This in turn would probably
reduce oxidative stress on bio-molecules (DNA,
proteins, lipids/membranes, etc). Less oxygen tension
in blood = less free radicals generated during
respiration.
