Microbiologist Giulia Enders is seriously into guts. So into guts in fact, that she's been the catalyst for a global movement to encourage people to understand their insides and to not be afraid of talking about them. Her book, Gut: The Inside Story of Our Body's Most Underrated Organ has sold well over one million copies in her native Germany and been published in over 30 different languages.

When Geena Davis was three years old she announced to her parents that she was going to be in movies.  In fact, the quote in her high school year book was "Future plans: go to the big city and become a star."

Fast forward some years and she's so much more. Fronting the Women's Sports Foundation and launching the Geena Davis Institute on Gender in Media - to name just a few accomplishments.
