Please add a list of your favorite documentaries in this thread. If you could, also specify whether it's a serious/scientific documentary or more lifted towards entertainment. (Both are fine btw, just helps to know beforehand what the documentary is like).
I am particularly interested in documentaries on nutrition, nootropics and neuroscience, and anything related to self-improvement, but enjoy just about anything.
I did a quick search on the site and couldn't find any threads about this and was hoping we could get something like this going.
