One estimate that I saw placed the number of possible sufferers at 20 million in the United States alone. I'm describing, tell your doctor to check for carpal tunnel syndrome and other hand-disabling problems that can result from keyboard work, such as tendonitis. And find ways to give your wrists a break when you are typing. You may even want to have the doorknobs at your home or office changed to levers so that you don't have to do a lot of twisting. And you might look, as I'm doing, for that electric pepper mill.
Some gadgets are just plain common sense.
