+  How old does code need to be before it's considered legacy?
+---
+
+How do you define legacy code?
+
+Code that was written by someone else?
+
+Code that doesn't have tests?
+
+Any code that has been released to production?
+
+Code that's more than a day old?
+
+In a talk I recently watched, the speaker suggested that any code written more than thirty minutes ago is legacy code.
+
+Once you've written some code and left it for half an hour, you need to re-read it to remember and re-learn what the code does and decide how you want to implement your next requirement.
+
+This is the same approach for code that was written longer ago or written by someone else.
+
+What do you think?
