I have a job very similar to this guy's - slightly more technical, I can build you the next myspace, but I don't know if I could build a fire in the wild.
I too enjoy Bear Grylls.
We all have our skills and interests.
I would get lost trying to understand your technical skills. It is interesting for me to watch skilled people in action.
However, I can build a roaring fire in no time even in a rain forest in the middle of a rain storm ( I have many times ). A skill that I do not use much anymore.
One of my goals here is to help the willing learn a few basic tips that may keep them alive in the future.
