Having a beer on his 90th birthday:
"In a recent interview with the Italian newspaper Il Messaggero, [Archbishop Georg] Gänswein said that as he turns 90, Benedict occasionally talks about the prospect of death, but it’s not an “obsession” for him.
“I can say that he’s a serene person,” Gänswein said. “He has a soul at peace, and a happy heart.”
These days, Gänswein said, Benedict can no longer see out of one eye, although that’s an old problem, and also has difficulties walking, but otherwise is in good health.
“Certainly, he’s a man who by now is old,” Gänswein said. “It’s tough on him to walk, and he uses a walker. He can’t work on scientific texts like he used to do, but he still writes, and a lot. He has an enormous amount of correspondence from all over the world. He gets books, essays and letters, and he replies. Naturally that takes time and effort, but he thinks about every response, it’s never something done casually.”
Gänswein also said that for Benedict now, his most important activity is prayer.
“He’s convinced that prayer is apostolate number one,” he said. “Through prayer, he feels able to be close to the faithful.”"
