Even at a fast walk of 4mph, that works out at three hours spent pacing around the living room every day. The retired tennis star – famous for his epic rivalry with fellow great John McEnroe, voted the greatest sporting rivalry of all time – is now approaching life "day by day". During his playing days he was also considered an international sex symbol, but the 69-year-old Borg has kept his life after tennis out of the public eye.
