Physiotherapist Daan Vermeulen helps an elderly man to feed his pig Felix in a senior care facility on April 12, 2011 in Essen, Germany. Vermeulen uses Felix, whom he has specially trained, to provide emotional therapy for the elderly and for handicapped children. He claims contact with the pig stimulates curiosity, activity and even alertness among elderly people and helps them to awaken from the passivity that often sets in as they become older.
