(see related stories) Vatican City, June 7 - Pope Francis said Friday his decision not to live in the papal apartments was dictated by "psychiatric reasons" - his aversion to living alone. After the Argentine was elected head of the world's 1.2 billion Catholics in March, he decided to live at Saint Martha's House, the hotel for Vatican visitors where he had stayed during the conclave, in one of a series of breaks he has made with Church tradition. "It's a problem of personality for me," Francis told a meeting of students from Jesuit schools. "I need to live among the people. If I lived alone, maybe a little isolated, it wouldn't be good for me. "A professor once asked me why I didn't live there (in the papal apartment) and I answered 'listen professor, it's for psychiatric reasons, because of my personality'. "The (papal) apartment is not so luxurious, but I can't live alone and I think that the times are telling us that there is a lot of poverty in the world and this is a scandal. "I, and everyone, must be as similar as possible to Jesus, who was the poor teacher".
