And here is Part 2: As you may know I consider Jeffrey Mann to be one of the most knowledgeable people I’ve met when it comes to golf swing mechanics. I have met with Jeffrey at his home twice and once on the driving range before flying out of Salt Lake City where he lives, and I admire his fascination (obsession?) with the workings of the golf swing. Jeffrey is not a good golfer, but he is an ultra-smart guy who has applied his experience as a doctor who cut up cadavers (he knows his muscles, bones, and connective tissues) and as a research analyst for some high -level science publications to figuring out the best way to strike a golf ball.
