I usually don't have an interest in sports (other than Formula 1). A live game of anything is always fun, but I have no drive to watch anything. Even during the Olympics, I usually will pause for a moment for something like gymnastics (how do they DO that?!) or Ski Jumping (WHY do they do that ?!).... just because it's such an amazing spectacle.
Yet now that I have a sport of my own, I found myself more interested in the Olympics this year. I watched some of the decathlon coverage, and they talked a lot about it being a competition against your own numbers, and your own fatigue. I understood.
This same week, I received my first issue of the IPF Magazine ( http://www.powerlifting-ipf.com/media/ipf-magazine.html - I doubt the link will work forever , but there you go...) One of the articles was about the IPFs drive to join the Olympics. Interesting journey.
Anyway, from Zero interest in sports, to both watching for fun, and getting a sports magazine subscription in the same week. Overboard?
