Thanks! But if I should tell you a secret: it was easy.
Would having a simple knife have changed what you did or how you did it?
I think the equipment that would have made things much easier would have been a simple fishing kit (some lures and line or a small net, etc). A knife would have allowed us to do more things, but not many things that was actually essential to survival or would have improved our life significantly. I think some would have loved a wool blanket, but I was comfortable enought with what I had. My thought on survival equipment is that you need to fix normal problems in the normal order:
1. Stay warm (i.e. decent clothes)
2. Sleep (here a wool blanket, sleeping bag, or some spare garments could come in handy)
3. Hydration (not a problem in Sweden, just find a lake or creek)
4. Food (eventually)
Actually point 2 is more important than people think, if you can get a decent nights sleep you are a useful, rational human being rather than an antisocial zombie. Then all else is surprisingly often solveable. I must redraw the Maslow hierachy to match this...
Did knowing you had a finite time for the exercise effect your decisions "it only has to last 14 days"?
Not really. In an indefinite situation the "no fish" situation would have been more severe. If i had not had a job (and wife) to get back to I would have been happy to stay another week (even if I would have been much weaker at the end, most likely). In these kind of situation I get into the "flow" of the situation, living in the moment and enjoying myself.
The weight loss is interesting, if you lost half a kg per day, this suggests something like 3000 calories difference between input and expenditure.
I checked the research data: on the average we lost 2% the first 24 h, and 0.6%/24 h after that (so about a pound/day for me), The initial loss was probably mostly things like glycogen and GI contents., after that it was fat & protein from the body. Also keep in mind that (at least initially) the utlization pathways are
probably [citation needed] may not be as effective as the regular "fat/protein from food".
