Janet, learning can manifest in numerous ways, not all of which require that you abuse an ailing body. Some who have heavily weighted their training toward the physical have neglected the mental/spiritual/philosophical aspects of the art. The later years afford the opportunity to bring back a balance. And there is also much that you can contribute to others through teaching. As for the physical, you will always be the sole authority on what is or is not good for you. Take ownership of that fact, and move forward without regrets.
