Did you know that around half of your body - possibly more - isn't even human? In How It Works issue 135, we explore the human microbiome and discover why we couldn't live without the trillions of bacteria, fungi, protozoa and viruses that occupy every surface inside and outside us. 

Also this issue, we speak to a space pilot to find out what it's like to fly a spacecraft, discover the killer properties of chemistry's deadly elements, go behind the scenes of the Silver Screen, how to talk cat, and much more.
