Before trying a hypoxic tent I wanted to measure the effects of altitude with Mother Nature. Besides, my wife said she isn t sleeping in some weird plastic tent or oxygen deprived room. Before leaving I arranged with my doctor to have a blood test and periodic follow up blood tests, using the common test called a CBC or Completed Blood Count. I also spent time in a military low pressure chamber where we experienced how goofy we would get with a lack of oxygen and experimented with grunt breathing at 37,000 ft. to stay conscious. When I was flying single engine military aircraft I used to watch flies caught in the cockpit roll on their backs when I depressurized the cockpit at 35,000 ft, only to come back to life again after landing when the pressure increased.
Flies are tough.
Put my food in the bear locker. No altitude sickness felt good. A bear tore a window out of the car by me and ripped out some of the upholstery looking for food. Local newspaper reported that rangers killed the bear 2 days later. Sleep 11 hrs - Slight headache and nausea from altitude.
