Is nostalgia a part of aging? Does it serve a purpose beyond reminiscing? Shiv and Sim discuss the phenomenon of looking back at the good old days, whether or not it's limited to people of a certain age, and whether it provides some sort of social function. They touch on Dr. Krystine Batcho's research on nostalgia, including the existence of different types of nostalgia. (Who knew that nostalgia could come in different flavours?!?). Join us as we chat about the elusive feeling of nostalgia and its impact in our lives on this week's episode of 'Does This Make Me Look Old?'.
