I'm always amazed at the lifespan of some of the code I've written over the years. I wrote an api that we use internally in 1996 that is still being used in all of our new production code in that language in our organization. I've learned a lot in the intervening 23 years so looking at some of that code can be a bit jarring. We've had to adapt it a bit when our environment changed a few times, and we've certainly added to it, but I don't think the core code has had any problems that I know of this century. Millennium, I guess, technically. Part of me really wants to rewrite it, but it doesn't make sense from a developer-time perspective (and I don't want to spend the time tracking down the inevitable bugs again).
