What I notice from this is that I'm a little longer, a little more grey, and a little more serene.
What would have happened if I hadn't kept up my practice for the last 10 years? No one knows the answer to that question. But, at 57 years old I hope I can show similar results in the next 10 years.
However, the most important practice is today. So it's just a good idea to get started when you can.
