I am not worried about much, but I do worry about cyber war. There is no consensus on what is acceptable in cyber warfare and all countries, including the US, are deploying cyber attacks. The best documentary to inform this worry is Zero Days, available on demand on Amazon, iTunes, GooglePlay, etc. Shows what cyber war is. Not sci-fi, but what is already here yesterday. With more to come! — KK

A few years ago, two gringos travelled to Central America and attempted to survive for 2 months on a dollar a day — as the locals do everyday. A diary of the visitors’ struggle is available on Amazon as a pretty eye-opening documentary, Living on One Dollar. Turns out it requires great skill to live on this little; the attempts illuminate the lives of the world’s majority in a vivid way I’ve seen nowhere else. — KK

A series I am binging on is Silicon Valley. I know all these people and every detail of their lives and situations is pitch perfect right on. The producers get the tiniest details exactly right, from the technology to the mannerisms, as well as their bigger narrative. I haven’t laughed so much in ages. At the same time, it’s a remarkably fantastic advanced class in what technology companies are really like. Whether you want to work in one, or start one: watch this series. — KK

My preconception of the mega-speaker Tony Robbins was shattered by a Netflix documentary on him. For decades I had the image Robbins as an over-the-top motivational speaker, a fast-talking get-rich salesman, a new-age be-yourself booster. But he is more of a fast-talking therapist or shrink. I really enjoyed the streaming doc I Am Not Your Guru and learned some things, although I still feel no need to attend his seminars. — KK

Les Revenants (The Returned) is a French supernatural television series (with English subtitles) that my wife and I are enjoying. The first episode opens with a terrible school bus accident in the alps that leaves 38 children dead. Four years later, some of the children return home, un-aged and unharmed. Spooky and fun. — MF
