I totally agree.I think that's one of the reasons that ice dance is one of the most successful disciplines — the skaters are around for at least two or three Olympic cycles.
It's especially bad in women's. I won't get into why since it will derail the thread. Suffice to say, I hope raising the age limit will have a positive impact.
It's what I worry about with the men now doing so many quads. How long can their bodies hold out? I think we're going to start seeing shorter and shorter careers, which is one of the reasons why I'm a proponent of limiting the number of quads (unpopular, I know).
