Meandering

I've had occasion to be concerned, over the past several years, that my mind seems to be slipping away from me — my memory, in particular. (Do you know that unsettled feeling when you walk into a room, but can't seem to remember why?) Lately I've come to wonder if it might not be a lack of mental activity, but a surfeit of it. That so many thoughts are wandering through my mind at any given moment that I am often easily, temporarily distracted, even in that brief moment it takes for me to wander from one room to the next.
