Former President George H.W. Bush showed his sense of humor about falling at his Maine summer home and fracturing a bone in his neck with a grin and two thumbs up.

The 91-year-old tweeted a smiling photo showing him in a neck brace and giving two thumbs up Thursday. He tells his followers, "Who knew jumping out of planes was safer than getting out of bed?" He also gives thanks for the "kind get-well messages."

The 41st president survived bailing out of his torpedo bomber when it was shot down in World War II and has skydived several times since then, including on his 90th birthday.

Bush took a tumble July 15 at his Kennebunkport home. Doctors are letting the fractured vertebra heal on its own.

During the winter, Bush lives in Houston.
