It's Okay to be Smart!

I admit that I am not a huge YouTube user beyond watching the latest Imagine Dragons video but I came across a GREAT channel provided by PBS Digital Studios. It is called "It's Okay to be Smart" and it has short, science-specific informative documentaries on various topics from why some people are left handed to why do people still deny climate science.  If you have a few minutes, it is well worth the time to watch. Videos last between 5 and 12 minutes.
