15>willYou

Once Mary heard a famous song, and a line from it stuck in her head. That line was "Will you still love me when I'm no longer young and beautiful?". Mary believes that a person is loved if and only if he/she is both young and beautiful, but this is quite a depressing thought, so she wants to put her belief to the test. Knowing whether a person is young, beautiful and loved, find out if they contradict Mary's belief. A person contradicts Mary's belief if one of the following statements is true: they are young and beautiful but not loved; they are loved but not young or not beautiful.
