Anyone works with old languages?

I work with COBOL for mainframe, since 1998.
Yes i am not kidding, i work with that old old old old language.
The mainframe was a IBM Z series, the 290.
Now i changed to other bank company and i will work with a new IBM, but the
language is the same... COBOL
Did you Know that more then 80% of world banks work with cobol as their main programming language?
