You know you watch too many survival shows when...
...you are in class explaining to your small group the pros and cons of keeping certain items from a fictional list in order to survive the longest on a raft, a thousand miles from land. For instance, we had to rate fifteen items in order of importance for survival and one of those items was 20 square feet of opaque tarp. Useful? They said no. I argued that with only 5 gallons of water for our whole crew it was crucial to have tarp. I went on to explain how to construct a water purifier from this by making a cone (or two, there was a lot of tarp) and placing a bucket of salt water underneath. The sun would then evaporate the water, leaving you with salt in the center and fresh water condensing on the inside of the cone. The water would then run off into the folded edges of the tarp and pool there for drinking. How do I know this? No clue. Dorky? Maybe.
I also had to explain how it was illogical to bring the map with us without the sexton. No one knew what a sexton was in any of the groups around me, which made me feel way over-prepared for class and for living on land. So we put the sexton as number six in importance and the map as seven. We naturally needed to know where we were in the ocean before we could use the map.
Needless to say, I felt very prepared to marry my future husband, Bear Grylls.
