This is all rather interesting - Al has reminded me of a guy I used to skydive with - Dale - who, even after 400 jumps, still entered the aircraft utterly convinced he was about to die, and was of course even more convinced by the time he CHOSE to let go (interesting, given the up-coming movie night...ALWAYS let go?). After landing, Dale was so 'rushed' that he shook like a leaf for 15 minutes after. This guy impressed me WAY more than the people who make it look easy. Over and over and over again Dale would take himself to the absolute limit of his capacity to cope, voluntarily. His body and mind would be on the verge of shutting down. You have to admire that in a person, whether it's YOUR limit or not isn't the point; it's personal.
Sailboarding - not quite the same thing, but there is an element of this too - everyone is, as Al points out, doing something different, yes, physically, but more so psychologically. Dale always reminds me that I cannot judge other people's choices about, for example, where they sail, or what they choose to do there. We are all going to a point and we each choose to define that point differently. The great thing is that the sport ALLOWS us each to define that point within the one common field - we share, despite the difference. I like to see other people enjoying it, and I like to be able to see that they are enjoying it for their very own, different reasons.
I have always enjoyed the 'edge' - not the 'wow that is so extreme' edge, but the edge of anything. I have also always liked the OTHER elements - air and water - getting out into those adds another dimension. The attached photo is a shot of 'Greenie' at Bellbuoy, heading out into what looks like a kind of violent sea - water and wind - electing to leave the land, to let go, to head out, if only for a few minutes. The edge of the land is the edge of where we 'belong' - beyond that...all bets are off.
Of course we don't all go sailing with the expectation that we are going to die, but we are almost certainly going to be beaten - the best you can ever hope to manage against Mother Nature is a draw. A humbling experience.
