Why do we get bored ?
VSauce is an interesting YouTube channel about psychology mainly. In each of them, Michael Stevens and his team explains some of our behaviours.
In an impressive one shot explanation, Michael manages to make us understand a lot of concepts while always citing his sources.
Some of his friends/colleagues also have VSauce channels (2 & 3) in which they show a lot of non-ordinary facts, objects that you can find in the world.
While number 2 & 3 are entertaining, I highly recommend the original VSauce because of its educative value.
