Neil Tyson and Dan Savage on "The Perfect Relationship"

Happy Valentine's Day! Love guru Dan Savage tells Neil deGrasse Tyson, Chuck Nice, and Dr. Helen Fisher what his recipe is for a successful relationship, what he considers the "price of admission" for a relationship, and why there's no "perfect" person out there waiting for you.

Plus, Helen explains the neuroscience of happy relationships and the importance of "positive illusions" - the simple ability to overlook what you don't like about a person and focus on what you do.
