Why do we collect things like Pokémon cards, old tea sets and comic books? According to Daniel Krawczyk, a behavioral and brain scientist — and pinball machine collector — collecting can help to connect us to our childhood selves, relive prior memories or recall happy moments. And coming together with fellow collectors in conventions or online forums can provide the mental health benefits of community, a chance to revel in shared expertise and share tips. Collecting may even have an evolutionary basis. We’ll hear more from Krawczyk and from you: What do you collect, and why?
