What is love? With half of first time American marriages ending in divorce by the 20th anniversary, and infidelity being widespread, Science Vs asks: have we been lied to by our love songs?

On today’s episode we explore: What happens to the brain when we fall in love? Is the compulsion to stay together biological? And, is monogamy really unnatural? We talk to Dr. Helen Fisher, Professor Larry Young, and Dr. Dieter Lukas about their labors of love.
