20. A Sore Hand

A: There's something wrong with my right hand.

B: What's wrong with it?

A: It aches most of the time.

B: What do you think it is?

A: I don't know. I think it's old age.

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.
