Bush is a fan of Associated Tennis Professionals (ATP) World Tour 250 events and lives in the Houston Area with his wife Barbara. He and his wife have attended many ATP fundraisers and charity events throughout the years. In good spirits!: Former President George H.W. Bush, seated, arrives just before the quarterfinal match between Jeremy Chardy of France and Kevin Anderson from South Africa was suspended by rain . Roy Emerson, 78, who owns 28 major singles and doubles championships, is also a big fan and makes an annual appearance at the tournament. Both Bush and Emerson enjoyed watching  Kevin Anderson of South Africa battle Jeremy Chardy of France before heavy rains postponed the game.

Bush spent Christmas 2012 in intensive care at the same hospital while being treated for a bronchitis-related cough and other issues. He was discharged in January 2013, after nearly two months in the hospital. Bush is the oldest living former American president. Because he suffers from Parkinson's disease, he is forced to rely on a scooter or a wheelchair.
