Sitting here in Pheriche, at 4270meters, I don’t care where you are in Canada or the lower 48, I am higher then you. We are higher then any mountain, or set of peaks, in the rockies. The air is thin, we are working with an atmospheric pressure nearly half of what is the norm in British Columbia, where we are from. For those of you who care, the barometer is giving me a recording of 562hPa. For each breath we take, we only get 2/3rds the oxygen in our lungs then at sea level. Everything is a struggle, and I mean everything. Walking to the bathroom renders you breathless. Brushing your teeth makes you gasp for air. The joys of altitude.
