This program offers a very unique look at the complex and mysterious workings of the human body. From babies to adults, men to women, athlete to musical prodigy - the science behind the body's amazing features are revealed. Why do opposites attract? What extraordinary sensory abilities do athletes, musicians and food aficionados have which allow them to excel like no other in their craft? How do the brain's one billion nerve cells somehow make chewing go faster when there's music in the air? Follow the fragments of a distant star as its energy reaches us and triggers chemical responses which provide pleasure, cure depression or change molecules to Vitamin D. This fascinating programme promises to be much more than a lesson in anatomy.
