Pope Benedict XVI recites the Angelus prayer from his studio window overlooking St. Peter' s Square at the Vatican, Sunday, March 18, 2012. Pope Benedict XVI has asked for prayers for his upcoming trip to Mexico and Cuba. Sunday marks the last time Benedict will greet the general public before his visit gets under way Friday. His traditional Wednesday audience was canceled for this week so Benedict, who turns 85 next month, can rest up before the long trip. (AP Photo/Pier Paolo Cito)
