Why do we have friends?

Friends rule! The best ones are those that are always there to help you out, embark on a strange adventure,  make you laugh so hard you cry and appreciate all the weird and wonderful things that make you… you! We love our friends! But do we humans need them as a species? We talked to psychologist/biologist Lauren Brent to find the answer.   Do you and your BFF have a question? Send it to us at BrainsOn.org/contact, and we’ll be a friend and help find the answer! See omnystudio.com/listener for privacy information.
