Just the other day I was wondering how close Dick was to having been Nightwing for longer than he was Robin, so I checked the dates and it's a lot farther than I thought. He was Robin for 44 years and became Nightwing 41 years ago, but if you subtract from that his time as Batman and "Agent 37" that's like another five or six years. Still almost a decade to go for his adult identity to be the bigger part of his existence, and that's assuming he doesn't get turned into something else or killed off or rebooted back into Robin somehow until then.
