That's probably about right. I caught the disease when I was 13, back in the mid 70s, and taught myself to program from wall charts and left over program listings while hanging around in a college computer lab. People were actually foolish enough to let me use punch cards, paper tape, mainframes, and other great stuff. If you haven't seen a card sorter, hand mounted a disk pack, or whistled a carrier tone, you haven't lived. :-)

I still love to code, and will continue to do it until I go blind and/or senile (no management for me) -- so I think it's terminal.
