Head held high, hands firmly gripping her walker, Mary Arnott, 99, walks slowly with dignity through the women’s changing room at the Etobicoke Olympium pool, past the teenage girls who have been blow-drying their hair for half an hour, into the mist of the showers, then out the door and first one into the heated pool.
