I'm right now sat on a comparably remote island in the Alaska fishery, relatively new here. I've always romanticized the sea, landlubber as I am, and after a few months here, I went to Waikiki for vacation and - hated it. I couldn't leave soon enough. Too much happiness. The people here have mostly been here for many years, and will remember someone they worked on a boat with for a few weeks in the 80s or what-have-you. I have time to read, be left alone when I want to be, grab a beer off-site. I can see why healthy people would go insane, and why insane people would go healthy.
