The time which one spends searching for the ancestors cannot be measured. That is because long before the body takes off on a field trip or searches records, the brain is forever working problems, ascertaining facts, recalling dates and places, and trying to discover answers. Searching for the ancestors is a blessed gift, because it teaches us to "remember." Anyone who researches a particular lineage does not have to continuously refer to notes. That is because the genealogy clock is always on duty, reminding. Reminding. How handy is it to visit the archives and while examining books and microfilm, recognize your people? As long as the dates are correct, we stay on track. Because it is so easy to get confused while we are tracing a generation of folks not within the scope of the correct time-frame. Because we remember the roads to the old ancestral homes, this sense of direction, combined with easy recall of dates and the frequent search for answers, spills over into brain power which is a good thing because it enhances the memory!
