A book jam-packed with insightful maps has shone a light on how the average penis size and average breast size differs around the world.
The book, 'Vargic's Miscellany of Curious Maps: Mapping Out the Modern World', has been created by 17-year-old student Martin Vargic.
The amateur graphic designer, from Slovakia, rose to international fame in January 2014 when he created a map documenting our differing behaviours on the internet.
His latest book contains maps detailing breast size...
Penis size...
And overall body weight...
As well as maps on our music tastes, average debt per person and more.
