Today, we would like to share with you an excellent animation published by NPR and created by Benjamin Arthur. Entitled “Exploring The Invisible Universe That Lives On Us — And In Us”, it explains the universe of bacterial life moving around inside us in a fun and attractive way. Take a look at this surprising video which, guided by Rob Stein, helps us understand the importance of the huge amount of “tiny little friends” that accompany us from birth.

We hope you enjoy it as much as we did!
