From birth, genetic females are better at fighting viruses, infections and cancer. They do better at surviving epidemics and famines. They live longer, and even see the world in a wider variety of colours. These are the facts; they are simply stronger than men at every stage of life. Why? And why are we taught the opposite? Drawing on his wide-ranging experience and cutting-edge research as a medic, geneticist and specialist in rare diseases, Dr Sharon Moalem reveals how the answer lies in our genetics: the female's double XX chromosomes offer a powerful survival advantage. And he calls for a long-overdue reconsideration of our one-sizefits-all view of the body and medicine—a view that still frames women through the lens of men. Revolutionary, captivating and utterly persuasive, The Better Half will make you see women, men and the survival of our species anew.
