1. Why don't they hurl or at least teeter after one of those blazing spins?
You do get dizzy, for a second or two, which is why skaters usually don't leap right into a jump after a spin. Instead, they take a few steps (strokes, they call them) to allow the fog to clear, and then plunge back into their routines (by the way, it's a program, not a routine). Also, most skaters, myself included, will tell you that they simply get used to the feeling. That said, Lucinda Ruh, often called the greatest spinner in the history of the sport, once told me that she routinely spun so fast--a physicist once calculated that the G force to her brain was akin to a fighter pilot--that she suffered mini concussions and had lingering effects, including vertigo and severe headaches.
