When you are born blind, you are faced with an incredible disadvantage. As much as we like to think that we live in an accessible world, life is unimaginably difficult for people who have to get through life without their eyesight.

But even if they can’t see, blind people come up with new ways to perceive the world around them with the help of their other senses. Take this man, for example. Watch what happens when he’s asked to draw things based on what he thinks they look like.

What an amazing experiment. Seeing how blind people learn to identify things around them is so interesting. This guy’s sense of humor is pretty great, too!
