Whether we know it or not we're all travelling on the same trackless way through the forest to a place we've never visited before. As for my knees, I feel they do their job. It's an interesting challenge living everyday as if it were my last. Some friends insist I live a more leisurely life. It's not my flavor.
Many people disapprove and so be it.
My life is a muscle, and I use it everyday. In your book, The Fruitful Darkness , you align perfection with being natural. Each endeavor enriches all the other endeavors. Steady practice twice a day is lifesaving. To be with people who are dying or in the penitentiary is lifesaving.
