as you can see, this might be nothing...or something. If it happens again, check it out. But many things happen which are hard to nail down...you might have had 2 or 3 thought processes going on which temporarily cancelled each other out. (That is a pretty strange and sudden way for a real problem to show up, which may be why so many make light of it...) If it IS a real problem, it would likely return and show more symptoms.

(Back to a lighter note...I have been saying that as I get older, my memory has become an integral part of my exercise program---living in a two story house, the more I forget, the more I run up & down stairs....)
