I was looking through my old video files and found this one about sleep.
It was made as part of a mini-video series that I called "Why We Love", which covered topics such as Why We Love Pizza or Why We Love Quotes. At the time (and still today) I was very interested in the topic of sleep, and decided to do some preliminary research and make an video about my findings. I talk about four theories for why we sleep, why we voluntarily delay our sleep, and dreams, among other things.
Here is the link to the original video on YouTube. Enjoy!
