Candy Spiegel, niche products editor for the Livingston County (Michigan) Daily Press & Argus, has written a great article entitled, "Genealogy is No Longer Just for the Elderly." She points out genealogy appealed to the elderly only because they had the time available to do the research. The advent of the Internet has changed all that.

Of course, as someone who started genealogy when in his thirties, I disagree with her statement of "Genealogy is No Longer Just for the Elderly." I never thought it was for older folks.
