We Jews are good swimmers, and the higher ranks of swimming champions are almost as packed with Ashkenazi Jews as chess masters and Nobel Prizes in Economy. Of course I was on the swimming team till age 21 and spent the summers as well-paid beach life guard. So it is no surprise that half of the world champion freestyle relay team is Jewish: Garret Weber-Gale (pic) and Jason Lezak. Quod erat demonstrandum. Phenomenal goy Phelps is an exception.
