We’re asking about your happiness, by the way, because a class at Yale University called “The Science of Well-Being” is now being offered online -- for free! The class is based off a course called “Psychology and the Good Life,” which became the most popular class ever taught in Yale University’s 317-year history, earning national and international media attention, according to Business Insider. Psychology professor Laurie Santos introduced the in-person version of the class at Yale, and she also teaches the online course.
