One good thing that comes from living the nomadic life demanded by an expedition is that one sheds the fake skin donned from living too closely among society. For those of us who live for the freedom of such a lifestyle, that skin is dry and itchy and ill fitting. From my observances, that skin is much like a callus caused by the pure irritation of being forced to spend so much time with one's fellow man. Thank God I am spared such nonsense.
