Out of Breath

Big Bob here. I was just walking to our room and noticed how out of breath I was. Now, I am unfit right now, but not that unfit! Then I remembered, we are at about 2300 m elevation, which for the Americans reading this is 7352 feet. By contrast, Ben Nevis, the highest mountain in the UK is 1,344 m (4,409 ft). The higher you go, the thinner the air and therefore the lower the concentration of oxygen. Hopefully we'll adjust soon.
