Pope Francis' papacy by the numbers

While many of his younger Italian brethren might still be sleeping, Rome's 77-year-old bishop is up at 4:45 a.m. and ready for another 15-hour day. Though he only has one fully functioning lung, he has maintained a rigorous and demanding schedule during his first 15 months of office, according to the Italian daily La Stampa, which published some interesting statistics on the pope that the Vatican confirmed.
