Yeah...but they are gonna have to hold onto it aren't they? (grin)
Altitude is a strong humbler. I have been gasping with my heart galloping and look over and some leathered up old Indian woman with a Bowler Hat and a Ruana (poncho) is walking up hill with a 60 pound sack of homemade charcoal on her back and a big fat handrolled stogie in her mouth and cheeks full of coca and acting like she could care less that the air is about 50% less oxygenated than at sea level.
Life is not fair in unexpected ways. It used to take me weeks to get really used to say 9K or above....and I would drop weight bigtime due to cardiopulmonary extra compensation. I have read that tall folks are more affected by altitude. I saw my dad get all goofy at Pikes Peak once as a kid and he flat passed out on his face at Mt Lemon in Arizona when I was a wee one and he was in USAF FS there.
At 0300L it was 120 degrees on the ramp when we climbed off our C-130. First few days we hid like rats from the heat and oven like sun. After about 3 or 4 days we started running & PT at night to minimize the effects. It still dropped a few of my troops and me with heat related stress and such.
Mother Nature will kick ya in the nads if ya don't respecte her 24/7.
Stay Safe !
