Walk and turn. >> This, can you say on this this ear >> [bell] >> or that? >> Okay. >> I can't hear on this ear. >> You'll be performing the walk and turn exercise first, and we'll use this white line to have you do the exercise. I'll demonstrate the exercise to you, give you opportunity to ask questions about the exercise, and then I'll have you do it. All right? >> This exercise is pretty straightforward. We provide information to take in. It's not meant to trick you or confuse you, but you do have to focus and pay attention to the to the information given to you. The exercise requires you to stand on line in position without moving as I'm showing you how to do it. >> Okay. >> That is part of the exercise. You must stand in that position while I'm showing you what to do. >> Okay. >> Okay? I'm going to start it out by having you do just that by taking your left foot, placing it on top of the line, and then placing your right foot directly in front of your left. I'm going to do it briefly so you can see what I'm talking about. Left foot on the line like so. Right foot in front of your left as your heel touches your toe. Once your heels are touching your toes, have your hands touch your sides. Stay in that position and don't move until I tell you to do so.
