I've always enjoyed watching the Olympics. This year my head was in a different place and I couldn't even muster the interest to watch summary shows.
Today I rekindled that interest a bit by going to the official Olympics site and learning of all the recognized sports. I had heard about the additions of surfing and skateboarding but a few sports evaded my lax radar. Such as: breaking (presumably dance), marathon swimming, beach handball, ski mountaineering, and roller speed skating.
I'm hoping in four years I will have the motivation to watch some of these events.
