Joining the ranks of modern myth busters, Dr. Sharon Moalem turns our current understanding of illness on its head and challenges us to fundamentally change the way we think about our bodies, our health, and our relationship to just about every other living thing on earth, from plants and animals to insects and bacteria.

So why does disease exist? Moalem proposes that most common ailments—diabetes, hemochromatosis, cystic fibrosis, sickle cell anemia—came into existence for very good reasons. At some point they helped our ancestors survive some grand challenge to their existence. Examining the evolution of man, Moalem reveals the role genetic and cultural differences have played in the health and well-being of various races, including their susceptibility to disease.

With mesmerizing insight, Moalem offers groundbreaking insight into :

• How diabetes may be a biproduct of a mechanism that helped humans survive the Ice Age

• Why African Americans living in the north might suffer from vitamin D deficiencies,

• Why Asians can’t drink as much alcohol as Europeans

Revelatory, utterly engaging, and timely—Moalem ponders strongN1, the emerging Avian Flu virus—Why Redheads Feel More Pain and Asians Can’t Drink will irrevocably change the way we think about our bodies and ourselves.

Was diabetes evolution's response to the last Ice Age? Did a deadly genetic disease help our ancestors survive the bubonic plagues of Europe? Will a visit to the tanning salon help lower your cholesterol? Why do we age? Why are some people immune to HIV? Can your genes be turned on—or off?

Survival of the Sickest is fi lled with fascinating insights and cutting-edge research, presented in a way that is both accessible and utterly absorbing. This is a book about the interconnectedness of all life on earth—and especially what that means for us. Read it. You're already living it.
