A couple of videos on the subject of “You.”

We think of ourselves as a single entity, but the reality is we’re a combination of trillions of individual organisms some of which are a part of us, but not human (e.g. the bacteria in our guts). So at what point do you stop being “you”?

The YouTube channel In A Nutshell has a new video out that’ll ask you to ponder: What are you?

If that’s not enough to get your head spinning, there’s a companion video by CGP Grey that talks about how you are really two “yous” in one body. Specifically, how experiments done on folks who have had the connection between their left and right hemispheres severed has revealed that you are literally of two minds that don’t always agree with each other.

Just some food for thought.
