B: If it's old age, why don't both of your hands hurt? A: That's a good question. Maybe it's not old age. B: Are you right-handed? A: Yes. All my life. B: You're wearing out your right hand. Stop using it so much. A: But I do all my writing with my right hand. B: Start typing instead. That way your left hand will do half the work.
