Bush in October joined the four other living former presidents -- Barack Obama, Bill Clinton, Jimmy Carter and son, George W. Bush -- for a hurricane relief concert in Texas. At the event, he was honored by his son.
The elder Bush has been hospitalized a couple of times this year. In January, he missed President Donald Trump's inauguration because of a 12-day hospitalization for pneumonia. And in April he was admitted to Houston Methodist Hospital again for a mild case pneumonia.
