Craig: from flip to flinch

"Flinch", "yips" in golfers, and a host of other movement disorders are now classified as a 'Task Specific Dystonia'
http://www.wemove.org/dys/dys_flimb.html The problem has ended the careers of some professional golfers and musicians. Aynsley Smith PhD, Director of Sports Pyschology and Sports Medicine Research at the Mayo Clinic, Rochester, and Dr. Charles Adler of the Mayo Clinic, Scottsdale have researched the problem extensively, and a 'cure' remains elusive.
Mine is so bad that I 'flinch' trying to click the mouse

A different issue is the anticipatory lunge forward in response to recoil. I briefly, in the mistaken notion that it would be fun, tried a .410 chamber adapter in a 20g and found myself shooting a foot under the skeet targets at station 2 from lunging forward against no recoil. No idea what the barrel was doing.
