Oh the irony!  Using the Internet to counteract computer-related health issues!  Well, the reality is that for those of us constantly on the keyboard—faculty, students, and all other modern-day workers—discomfort in the hands, wrists, and arms is common.  Eventually, discomfort can lead to more serious health issues, such as tendonitis, carpal tunnel syndrome, and other repetitive strain injuries (RSI). 

Check out this YouTube vodcast. Created by percussionist David Kuckhermann, it shows several very simple stretching exercises that can ease the discomfort and, hopefully, stave off those more serious conditions.

Once you learn the exercises, listen to some of the drumming videos on his frame-drums Web site!  Awesome world music!
