Join Katharina Vestre on an adventure to relive your very first moments. From your first cell to your first breath, this is your story as you have never heard it before. Did you know it took three attempts to make your kidneys? Or that tiny twirling hairs on your back showed your other organs where to go? Or that hiccups are probably a legacy from our ancient, underwater ancestors? With cutting-edge science and a wry sense of humour, Vestre reveals all this and more. Like: how sperm know which way to swim. Why sex and gender are more complicated than one might think. What you have in common with every living being, and why you are unique. Set off on a true voyage of discovery through an inner universe whose secrets we are still unravelling. A miniature drama of cosmic significance, this is the story of how you became you.
