A health problem resolved! It's finally been determined that my mother's heart is in need of mechanical assistance. After an interminable time suffering with black outs, etc., she is to get a pace maker. It will be a fine day when, recovered from the operation, she can enjoy a walk across the Common once again with her dog. It helps the concentration too, to know that she is being offered a solution to an ongoing problem. Silhouettes, you will soon have my undivided attention once again.
