That's very cool! I love to see what hidden talents or professions people have. I've even started a thread about it a time or two because I like to see what people do when they are not lurking around in here. I seem to remember there are a couple of rocket scientists among us. Not literally, but you know, similar professions.
That's true, Murray. It's sometimes a matter of natural talent, but also the ability to concentrate and learn new disciplines. People who can't settle in and concentrate have issues learning to do anything well. Plus you can't be super lazy, obviously.
