KJ- love that quote!! It is so true. My H also seems to have lost concept of time as well. And I would have to agree that my concentration is not as good as it has been, my memory is not quite as good. I know that mine is stress related and just the emotional exhaustion. I have been trying to search out a new job/possibly career path and I have thought about going back to school but really don't know if I have that level of concentration back yet.
