All good thoughts. Location is the only thing that I can add to the list. About half the posts come from people in the witness protection program or something. They don't want to reveal their location on the planet. Sometimes elevation and climatic conditions are factored into my answers. I once accurately diagnosed a problem and told the guy that my answer was based on where he lived which happened to be in Texas. I know Texas has a very humid climate in some areas. The guy didn't have enough of a clue to ask me what living in Texas had to do with his problem,
Notice the light isn't on.
