Maybe what it is is that you really like to see connections between things. This is like really what motivates me in science actually too. But it's like when you start recalling the past to, you know, and seeing the connections between the past and present,

But when you can look back at, let's say you hear a song that you used to play before you would go do a sports thing or something like that, and you might not think of yourself as an athlete, but once you get back to that, you mentally time travel to that particular thing, you open up this little compartment of yourself that wasn't there before, right? That didn't seem accessible for us.

Dan Schachter's lab did this really cool study where they would ask people to either remember doing something altruistic or imagine doing something altruistic. And that act made them more likely to want to do things for other people. So that act of mental time travel can change who you are in the present.

Yeah, so my friend Philippe de Brigarde wrote this, and it just blew my mind, where the word nostalgia was coined by a Swiss physician who was actually studying traumatized soldiers. And so he described nostalgia as a disease. And the idea was it was bringing these people extraordinary unhappiness because they're remembering how things used to be. And I think it's very complex.
