The bananas we eat today aren't our parents' bananas: We eat a recognizable, consistent fruit that was standardized in the 1960s from dozens into one basic banana. But because of that, the banana we love is dangerously susceptible to a pathogen that might wipe them out. That's the story of our food today: Modern science has brought us produce in perpetual abundance--once-rare fruits are seemingly never out of season, and we breed and clone the hardiest, best-tasting varieties of the crops we rely on most. As a result, a smaller proportion of people on earth go hungry today than at any other moment in the last thousand years, and the streamlining of our food supply guarantees that the food we buy, from bananas to coffee to wheat, tastes the same every single time. Our corporate food system has nearly perfected the process of turning sunlight, water and nutrients into food. But our crops themselves remain susceptible to nature's fury. And nature always wins.

"The Man Who Touched His Own Heart tells the raucous, gory, mesmerizing story of the heart, from the first "explorers" who dug up cadavers and plumbed their hearts' chambers, through the first heart surgeries-which had to be completed in three minutes before death arrived-to heart transplants and the latest medical efforts to prolong our hearts' lives, almost defying nature in the process. 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"--
