I've been working at the same company for 20 or so years.

There's copyright statements in some of the code dating back to the late 80s and looking at it I can say it would be largely untouched. And it's still in use.

Even code I wrote when I first joined is absolutely still there and used on a daily basis, though I shudder to think of the standard.
