Having been studying the “Frozen Shoulder Workbook” recently in search of a solution for recurring pain in my mouse-hand shoulder, this item caught my eye today. Seems researchers found that, while Pitching Changes Little Leaguer’s Shoulders and some of it results in long-lasting protective changes, too much is a bad thing. Some kids are playing lots of games all year round and are getting into painful situations. Better to vary the sports a kid plays, they say–and even just quit sports for a while and go be a kid (which is not to suggest spending endless hours on video games–which has its own set of perils).

The answers always seem to head in the direction of “moderation in all things.” Not very exciting, of course, but fairly reliable.
