Nostalgia is not the most toxic impulse

# Stuff You Should Know: Nostalgia

Josh and Chuck explore the surprisingly complex emotion of nostalgia, tracing its origins back to a 17th-century Swiss doctor who first identified it as a disease among homesick soldiers. They dive into what modern science has discovered about this universal human experience, examining everything from how music and scents trigger nostalgic feelings to studies showing it actually makes you feel warmer and more connected to others. Fair warning: their colleague John Hodgman believes nostalgia is toxic, so they spend considerable time either proving him wrong or at least having fun while the guy gets increasingly annoyed.
