Video: Your Brother's Keeper?

Time magazine science writer and New York Times best selling coauthor of Apollo 13 takes us deep inside  ourselves in this very revealing book on siblings. Grounded in authoritative  science, Jeffrey Kluger investigates what recent developments in  psychology, biology, and sociology convey about these often complicated  relationships and the profound influence our brothers/ sisters have on our  own personalities. Kluger translates complex, path-breaking scientific  discoveries into accessible, witty, emotionally engaging stories that readers  can grasp, embrace, and - most importantly - PUT TO USE IN THEIR OWN LIVES.  THE SIBLING EFFECT is, at once, deeply personal and universally useful,  entertaining, and instructive. Kluger writes: "The sibling experience  powerfully affects almost all families, and the effect continues later and  later in life. Towards the end of our lives these are the relationships than  can sustain us... these people who've known us the longest, loved us the  hardest, and also know us the best".
