I had to look it up as I don't watch TV. Initially thought you were selected for the show, but that should be interesting. My sister was trekking across Central America not that long ago and she said there was also a couple doing it as part of their honeymoon (if you can find a woman who will accept a kayak in lieu of a diamond ring, let me know). No showering for about a week+, yup definitely test the boundaries of any relationship. On a side note, I really enjoyed reading "66 Days Adrift", an extreme example of survival. It talks about a couple who lost their sailboat and were stuck on a life raft for 66 days, surviving on sea creatures and fending off sharks. That would definitely test the boundaries! Sadly she divorced him after that ordeal.
