For me, it means I need quiet to be able to truly focus on the task at hand. I used to be able to eat, listen to talk radio, drive and read a map at the same time with the air conditioning blowing full force. Now, if my wife is driving and needs directions, we need to turn of the radio, turn down the A/C, and usually pull to the side of the road so I can concentrate to read the map. I am not even driving but still need to stop the motion so I can read the map.

If I am trying to fill out a form with lots of blanks to fill out ( like today at Urgent Care as I was getting ready to have 9 stitches in my hand), I need to cover the bottom of the page so I cannot see the lines below the line that I am working on.

Or, ear phones/head set so i can hear the TV voices.
