Closing your eyes gives you more brain power for concentrating on what is being said. When I was in college I was required to attend a concert where they were banging pipes, breaking glass and ringing bells. It was suppose sound like music, but to me it was just noise. I had a terrible migraine so I leaned back in my seat and closed my eyes, suddenly it sounded like music. I was so busy watching all the activity that my brain wasn't putting the sounds together. I don't know if this happens to people without MS. Potter

Hi @peterfrancis I agree with @potter, there is one thing you have to bear in mind though, it drives my wife nutty she get the impression I'm not talking any notice of her. Oh open or shut Jazz is just wrong, far to busy. Keep smiling
