I mainly watch some of the fluffier informational content like semi-educational youtube videos and documentaries as a blend of relaxation and low efficiency passive learning.

I find that information density and technical depth are inversely proportional to my ability watch this content when I'm trying to relax or if I'm tired :)

Not a terribly surprising finding, but I'm glad some of this "more digestible" informative content is increasingly available. I'd usually rather watch that type of stuff than most fictional shows. I do like a good novel now and then though.
