Betty, what's the matter?
Well, at the end of the day at work, my neck really hurts.
I see, do you do a lot of computer work?
Well, yes. I spent all day at the computer, but I take regular breaks.
OK. That's good, but do you relax your arms?
Sorry?
Well, every half hour you should relax your arms to reduce the pressure on your neck.
I see, I can do that I guess.
