Whatever! You are never to old to start dancing.
A lot of people start very young, and you are not going to be as good as them at first, and maybe even never. But really, it is worth a try. No matter what, dancing is one of the greatest feelings in the world, as I am sure you know.
It will be harder to train you feet and get the flexibility than if you started when you were younger, because thats when you are growing into your body and it just comes more easily, but by no means is it impossible.
