How much of the world around us is invisible? It seems like a silly thing to think about. And it is. But that doesn’t mean it isn’t interesting. We can’t see many of the things we know to exist. Isn’t that strange?

In this video British comedian John Lloyd ponders the invisible. He lists the many things in our lives that we can’t see. There are so many funny and interesting stories surrounding them. By the end, you’ll have more questions than answers. But you’ll have had a good laugh. And maybe your sense of wonder will be renewed.
