Excuse the advertising but I saw the above video of Bill Shannon a while ago and his movement is wonderful, I read somewhere he has a degenerative hip condition, however he moves with grace and with his crutches he can do things those without cannot.
In the lecture below he brings up the interesting, enlightened and funny phenomenon of naming of techniques and accepted movement. At 12min 50secs he discusses people watching others, however not from a admiration point of view but as if they were helping or acting out helping. This is akin to when I watch rugby or other sports and my body kicks or convulses in response to the action or the action I wish the player had made.
Interesting that some people see him move and think he faking, and so what if he was, just highlights some movements be it fidgeting are frowned upon and people feel the need to judge.
When I attempt to teach people to kayak, to me its not about static postures and strokes but flow.
Regarding staring, I think there are many layers. You are seeing something which is nice, its human nature to do so and human nature to wince and look away from other things.
