The Man Who Touched His Own Heart

Thought of as the seat of our soul, then as a mysteriously animated object, the heart is still more a mystery than it is understood. Why do most animals only get one billion beats? (And how did modern humans get to over two billion, effectively letting us live out two lives?) Why are sufferers of gingivitis more likely to have heart attacks? Why do we often undergo expensive procedures when cheaper ones are just as effective? What do Da Vinci, Mary Shelley, and contemporary Egyptian archaeologists have in common? And what does it really feel like to touch your own heart, or to have someone else's beating inside your chest? Rob Dunn's fascinating history of our hearts brings us deep inside the science, history, and stories of the four chambers we depend on most.
