I wanted to know what you meant by professional. Why you infer any hostility in the question is rather beyond me. The word "professional" tends to mean someone does something for a living, ie makes money doing it, and I was wondering if that was what you meant, because so very few of us are lucky enough to land jobs that allow us to do it on the job - I figured you were out following Andrew Skurka around, or filming Outward Bound trips, or maybe one of those "reality" survival guys.
