I find it is often thirds who are the hottest. Not sure why that is. Leads and seconds have to be the most athletic. Thirds are a little less athletic although not by a ton. But they just seem to have a sexy bitchy attitude. That has been my longterm observation.
Being skip is, by far, the least athletically demanding. These days, some keep in really good shape anyway. Chicky-poo up top seems to be case in point. But some skips don't bother as much. Canada's skip at these Olympics, Jennifer Jones, has kinda let herself go in that regard. She has been around a long time and has always had a reasonably nice face but her body just ain't happening any more.
Our skip in 2010 at Vancouver was a fitness nut and it showed.
