Bruce, your theory makes a lot of sense! Just like they say a person who acts as their own lawyer has a fool for a client, I think the same way about a person being their own pilot, unless they have a qualified copilot along in case something goes wrong! And what about people trying to be their own doctor? The only field where the do-it-yourself method makes sense, is being one's own "Dr. Kevorkian" , if you mess up, you LIVE! Make sense? Ken B
