“Just walk it off.” If you are roughly my age or older chances are almost certain that you’ve heard this at some point in your life, be it directed at you or otherwise. Maybe you got a scrape on your knee falling off a bicycle, I certainly had plenty of those. Or maybe you landed badly on your ankle and twisted it a little trying to catch a ball, I had plenty of those as well. Or maybe you’re a Major League caliber player coming off an All Star season where you were one of the best hitters in all of baseball who has been struggling to produce hits.
