Timber (TAG) is supposed to be about 5. He is a rehome, so I will never know for sure. All I do know is that he is an adult and not a baby! If you are concerned, there are things you can do to help your bird live a long life. See the threads about diet, lighting, etc. If you have already done so, I apologize, but you never know. Birds, like people and other pets, can die before their time from disease, genetic defects etc. I just pray over Timber daily and do all I know to do to give him what he needs to thrive.
