That I can handle... I used to spend some time alone when working for the Australian DOD... months alone with just a few guys. You get used to it pretty quick, and the isolation.
These days... as long as I had the missus, a doona or two (or three) and an endless supply of coffee, would be an adventure. I would love to be outside though, that would kick arse being out on the ice, all that white, no noise. I would love to visit the North or South poles... would be an awesome adventure... still scary, yet so thrilling.
