I'm in my 60s and now I do comment, spell out descriptive variable names, and indent. I really miss the "old" days... when I wasn't so damn old!
Mt database stuff was probably around 50,000 records, so we are miles apart in this area. You may want to start up a discussion with Steve, just on managing techniques. I don't think he has worked with MySQL, but he has worked on some commercial billion record systems.
