When I'm in the general vicinity of one of my rink hangouts the sense of skating is palpable, although I have a tough time explaining why my heart quickens. Nearby skaters are constantly working very hard and seriously with perceivable bodily risk. It's a similar flavor to hanging out near a hospital: it's the sense that extraordinary people are doing incredible things to make the world better, in small ordinary ways. Part of it is the aura from the class of people, some of it is the relief and change they make in the world.
The reason a gal becomes a figure skater feels obtusely parallel to the reason a guy becomes a doctor, along with its accompanying misdirections, temptations, and sorrows. They all have immense concentration to start with, but it takes a very strongly focused personality to be top-level successful in either occupation (a maniacal and extraordinary sort of driven being). I never witnessed this level of total dedication with my friends in other sports -- they were more just very serious jocks, like those of us who were deeply into science.
Skaters are much more than that. They are the doctors of athletes.
