I also had training in the Marine Corps when I went through Pilot survival school on how to construct a source of communication should my own radio be lost or destroyed if I had been shot down over enemy territory.

Well exactly! It's all got so high-tech these days that many of us just wouldn't know how to build a fire to make a cup of tea

(see? there I am stranded on an island - was I making a fire to signal for help? Was I making a fire to cook some food? (Bananas make a great veg if they are very green), Nope! I was making a cup of tea

On a slightly more serious note, for me this would be about leaning how to make a radio receiver as a starting point for going on to build a transmitter... so Ed... when are you flying over to teach me? I was in the guides as a child and learned a lot of basic survival skills (that I then used to rescue Mark from drowning in a feather bog on Dartmoor

) but they were a little girly! For instance, I can make fires, and all sorts of little camping gadgets out of natural materials, but could I construct a communication device? Nope. Presumably we were supposed to remember to take some boy scouts with us to do that sort of thing

Perhaps we could make a forum TV show based on LOST and featuring us (I can see it now, instead of investigating the clanging noises coming from hatches and underground territory, once we'd got some hot water for that tea I was talking about earlier, we'd be looking for ways to make cards !!!)
