The expression "not be getting any younger" means that a person is aging and getting older. It is often used to suggest that someone should do something soon before they become too old to enjoy it. For example, if someone says "I've always wanted to learn to play the guitar, but I'm not getting any younger," it means that they should start learning soon because they're not getting any younger and it may become more difficult as they get older.
