Former President George H.W. Bush gave a "thumbs up" in a tweet to supporters Thursday, two weeks after he fell at his summer home in Maine.
Bush, who has a form of Parkinson's disease, showed his sense of humor about a spill he took at his home in Kennebunkport on July 15 that fractured his C2 vertebra just below his skull.
Doctors said it didn't impinge on his spine or cause any neurological impairment and will be allowed to heal on it's own.
In a tweet Thursday, the 91-year-old thanked supporters and quipped, "who knew jumping out of airplanes was safer than getting out of bed."
The nation's 41st president survived bailing out of his torpedo bomber when it was shot down in World War II and has gone skydiving several times since then with the Army's Golden Knights, including on his 90th birthday.
The former president's neck injury could take up to four months to heal, said Dr. William D'Angelo, a neurosurgeon who is treating Bush.
