If you're like me, you'll often find yourself neglecting homework for your calc/chem/etc. class late at night to instead watch food documentaries on YouTube in eight parts, justifying yourself by saying that it's just another form of education, and is equally as important. We could go back and forth about which is more important all day, and I'm definately not encouraging anyone to neglect their homework to sit in front of a computer screen for an hour or so, but if you have the time and you're interested, I would definately recommend watching these, they are the best I've found.
