I'm curious, do we have many students here who participate in school / college / university sports teams? My wife and I ate dinner in our college's dining hall today. (She teaches German here, and this year started to have her weekly "German table" at dinner instead of lunch, by request of her students.) I was struck by the number of students wearing warmup suits for one of our sports teams. It turns out that about 1/3 of our students are on one of those teams. This is for competition with other schools, not including intramural teams that play only each other on campus. I suspect this is fairly typical for small colleges such as ours (1100-1200 students). At large universities the fraction is surely much lower. Some of our physics majors are in fact also athletes. The fraction is somewhat less than in the general student body, but probably averages around 1/5 to 1/4. We regularly talk to prospective students that are being recruited by one of the coaches. I know that this strong emphasis on athletics at the college/university level is probably peculiar to the U.S.
