Former US President Carter recovering from surgery

The Carter Center, his charity group, said there are "no complications" following the surgery. It said in a statement that the ex-president will remain in Emory University Hospital "as long as advisable for observation."

Carter, 95, was admitted Monday night to the hospital after recent falls he sustained resulted in brain bleeding, according to the group.

Carter had fallen at least twice last month, with one incident requiring him to receive 14 stitches above his brow after he hit a sharp surface. The second fall resulted in Carter receiving treatment for a pelvic fracture.

Carter is America's oldest living former president, and had already received treatment for liver and brain cancer. He was cancer-free four months after beginning treatment.

But despite his health challenges, Carter has remained committed to a life of voluntarism. He has maintained his strong presence with Habitat for Humanity, the nonprofit committed to building homes for those in need, and as recently as last month he traveled to Nashville, Tennessee to help with one of Habitat's builds.

That visit coincided with the same week Carter received the stitches to his face, but at the time Carter reportedly said with a blackened, swollen left eye that it was a "number one priority" for him to be at the site.

Beyond his voluntarism, Carter still takes the time to teach Sunday school twice a month at Maranatha Baptist Church in Plains, Georgia, his quaint hometown.
