I get asked almost daily “Am I too old to learn to sing?” And the answer is absolutely not!
The voice is a muscle (actually a group of muscles), and like any muscle in your body, with good training will grow even into your 70’s.
Obviously not as quick and robust as in your 20’s, but grow it will if you are willing to put in the time and effort with proper training.
Take it from me, Old Guys Rule!
