I too was born and raised in Florida. As a matter of fact, in Walton County which has the highest elevation in the state.

I know it is less than 400 feet. As a matter of fact, while driving to DeFuniak Springs I pass several places well over 300 feet. That is according to my Garmin.

Ii doubt if I could breathe above 10,000.

You’d be surprised

I spend at least a month a year up high

Two remedial open hearts and a pacemaker

And I function fine in Santa Fe and Aspen and Gunnison even Leadville and Alma and West Yellowstone

Give yourself a day or two to acclimate before you jog Argentine Pass near Leadville

Or Mosquito Pass

I go pretty high for me. 13,500

I wouldn’t want to live there but I do surprisingly well

And if I dropped dead

Prolly second best way aside from dying while cracking

That or sailing a nice Swan into the wave of the century

When younger I walked/climbed the Sierra Nevada near Santa Marta and some lesser peaks around Guat and Nica and Bolivia

I used to smoke marlboros at 17500

Got a bit light headed

I’ve seen tapes of Yosemite hippies on El Cap nose drinking and smoking herb and cigarettes while tied off or wall camping like that pic up thread

Crazier still is a film I saw with a Russian super aplinist on K2 or Annapurna smoking Russian non filtered cigarettes at 24-25,000 feet

Humans can do a whole lot

Most of the early white climbers and all the Sherpas smoked cigs back in the woolen and hemp era
