It happens once every four years: we find ourselves suddenly riveted by a curling match or luge competition or ice dance that we wouldn't normally give a second glance. It's a tell-tale sign that it's Olympics time, and this week marks the start of the XXII Olympic Winter Games in Sochi, Russia.

Before 2014, the highest level of competition women could reach was the Women's Ski Jumping World Championships, and that's only taken place since 2009. This year the high-flying ladies are in the Olympics competing in one event (their male counterparts do three). Hopefully it's just the beginning.
In 2013, Russia banned what it called "gay propaganda" so the U.S. chose an Olympic delegation that included openly gay athletes but no Obamas or Cabinet members. Find out who will be representing the USA in Sochi.
