Bytes are cheap, thumbs are not and actually, your thumbs do not need the exercise. Each extra space is an extra push with your thumb. Unfortunately most of us use less than efficient movement when we are keyboarding away and we tend to suffer from (pick your ailment): sore wrists sore elbows fatigue sore fingers trigger fingers sore neck blurred vision lower back discomfort TMJ So, don't be so cavalier about your thumbs, find your nearest Feldenkrais practitioner and sign up for lessons. You will be amazed at how the process helps you to work more comfortably at your computer .
