Our relationships with our brothers and sisters can have a profound influence on who we grow up to be, says author and editor-at-large for Time magazine, Jeffrey Kluger. In this popular TED Talk, he reflects on how our siblings shape us across the different decades of our lives. He also touches on topics such as birth order, favoritism and sibling rivalry. “Our parents leave us too early, our spouse and our children come along too late. Our siblings are the only ones who are with us for the entire ride,” he says.
