Another hospital visit

My dad is back in the hospital, and while not dire, it's not great news either.  It almost certainly seems to be the heart.  Congestive heart failure can be a condition with which a person can live, but in Dad's case, it's just not good.  On the upside, he currently seems to feel better than just this morning, and hopefully it will be a short visit and he can be home resting before too long.
