It's worth noting that Nicholas Johnson, author of the book Big Dead Place [1] and editor of bigdeadplace.com, committed suicide [2] in 2012. He had just been rejected [3] from another contract in Antarctica.
> You may believe that you are only going to Antarctica for one season. Though that may be true, it is not. Antarctica will pierce you in the heart, and even if you don’t come back, you will think about it off and on, probably for the rest of your life.
