That's a funny statement
I'm sure-ish some of my code from 10 yrs ago is still in production. Though I'm far removed from where it actually runs. Maybe even some of the older code I wrote (which at this point is ~ 15yrs old) might be still around (at a different place)
5 yrs ago? No problem. I even have to still maintain the darn thing.
Of course, different companies, different cases, etc.
