Think you know all about the Olympics? I'm betting a few of these facts will blow your mind.

Do you know who the oldest gold medal winner is and how old he or she was?

Do you know what the medals are made out of?

Do you know what new metal will be added to the gold medals this year?

What year was China's first medal won?

What was the year of the first winter Olympics?

I could go on and on but just watch the video above and watch the Olympics which begin with the opening ceremonies on February 7th, 2014.
