During his life, he frequently traveled, which he loved to do, visiting friends in Cape Town, Europe, and Canada. In 2007, he traveled to Tibet, making it up to the base camp of Mt. Everest. His favorite place of all to visit was Venice, Italy. Michael enjoyed playing the piano and working in his garden. He also very much enjoyed opera and classical music, often attending local performances. He also funded a ten-year scholarship program for opera at his alma mater, the University of Cape Town, which was one of countless acts of generosity Michael showed to others throughout his life.
