Nostalgia - It's delicate, but potent...

"Nostalgia - it's delicate, but potent. Teddy told me that in Greek, "nostalgia" literally means "the pain from an old wound." It's a twinge in your heart far more powerful than memory alone. This device isn't a spaceship, it's a time machine. It goes backwards, and forwards... it takes us to a place where we ache to go again. It's not called the wheel, it's called the carousel. It let's us travel the way a child travels - around and around, and back home again, to a place where we know are loved."

Don Draper, Mad Men
