I'm going to comment on Count Yogi for possibly the last time. My right thumb was nearly chopped off 4 years ago and recovering from that has been challenging, keeping me away golf, for the most part. Some days my thumb moves and feels almost normal, other days it barely moves while throbbing from nerve damage. But I do vividly remember when I played and practiced golf almost daily using the CY method. There are indeed physical aspects to this system. Grip and where to place and align the body, feet, and especially the clubface are all dealt with. And it is not nearly so radical in approach as it may have once seemed. Tiger Woods and many highly skilled golfers today finish their full swings with the club wrapped around their necks, pointing forward, which is what CY advocated decades ago!!! That was believed to be dead wrong for a long time, with a "high finish" or "reverse C finish" considered much more acceptable. In "5 Simple Steps to Perfect Golf" and the excerpt from it in the more recent "The Secret of Golf" anthology, specific physical motions are described by CY as being optimal to a good swing. However, CY also stated that no two people can ever have the exact same backswing and swing arc, simply because of physical differences between us all. There is more common sense and much less mysticism to all of this than skeptics and detractors would have you believe.
