Recommend some fun documentaries?

Hey there,

I was wondering if anyone could recommend some fun and light-hearted, but still insightful and thought-provoking documentaries. Basically, a documentary about an issue, but an optimistic and fun documentary. I typically try and watch 2-3 documentaries a week, but I tend to watch more serious and brutal stuff (documentaries about child slavery, factory farms/animal testing and so on). But I find myself super burnt out these days, partly from watching super serious documentaries, and other stuff. It becomes mentally exhausting, frustrating and almost depressing after a while. So, watching some more inspiring and uplifting documentaries would be cool!

Here’s some documentaries I’d recommend:

“We the Tiny House People: Small Homes, Tiny Flats and Wee Shelters”: http://www.youtube.com/watch?feature=pl ... DcVrVA4bSQ

“The Witness”: http://vimeo.com/5209895

“The Emotional World of Farm Animals”: http://www.filmsforaction.org/watch/the ... mals_2004/

“Small Kitchen, Big Impact”: http://www.youtube.com/watch?v=o6XEeu6T ... o__G04_Kma
