Here's a bit about it:
Built from the debris of exploding stars that floated through space for billions of years, home to a zoo of tiny aliens, and controlled by a brain with more possible connections than there are atoms in the universe, the human body is the most incredible thing in existence.
In the sequel to his bestselling Inflight Science, Brian explores mitochondria, in-cell powerhouses which are thought to have once been separate creatures; how your eyes are quantum traps, consuming photons of light from the night sky that have travelled for millions of years; your many senses, which include the ability to detect warps in space and time, and why meeting an attractive person can turn you into a gibbering idiot. Find out more at the book’s website.
Bursting with eye-popping facts and the latest mind-bending theories, the book takes you on journey through the mind-boggling science of the human body:
Every atom in your body was either produced in the Big Bang 13.7 billion years ago or made in a star between seven and twelve billion years ago
Your body contains around 10 times as many bacterial cells as it does human cells
When you make a decision to do something your brain fires up about 1/3 of a second before you are consciously aware of making the decision.
