I don't think that bravery is about skin. Bravery is about a willingness to show emotional need.
I go on expeditions for the same reason an estate agent sells houses - to pay the bills.
I would venture to guess that if I was a construction worker... who requested a transfer to another department for the betterment of his family, I would be commended for it. But because it's sports, there's just so much passion added to it.
