This is one of the main reasons that "older" hikers/climbers have LESS trouble with Acute Mountain Sickness, or even simple "Mountaineer's Foot."

Younger people may have more reactive vasculature, ie hypoxic pulmonary vasoconstriction (HPV) that is important for HAPE,
but experienced-based pace is important for reducing risk of AMS, HAPE, And HACE.
