Personally, Jack, I would prefer to do another quiz. Unfortunately, the last few that were run were primarily me and Ernie trying to "stump" each other. It would be a lot more fun to have at least 5 or 6 people trying to figure it out, hence the "do we keep going?" question.
As far as an age thing, I'd have to say NO. There are several sources of information out there that can be used to do a quiz, I use primarily two of them. The "lack of interest" in the younger generations could be an issue though, when you really look at it. Many don't want to get involved with something where they actually have to think. I see this every day at work, younger people wanting to be told what to do rather than having to think for themselves
