Federico Lombardi, Vatican spokesman, said the pope is in generally good health for his age.\"He is currently studying the possibility of going to Mexico and Cuba in the spring, which I think is rather more important,\" he told The Daily Telegraph. \"His state of health is fine and he is able to carry out his duties.\"Benedict, who suffered a mild stroke in 1991 when he was a cardinal, has said he would step down from his post if he became incapacitated.
