So, for this next test, what I'm going to have you do, it's called the one leg stand test. What [bell] I want you to do is you can choose any foot you want. If you could just bring your feet together and arms down at your side. What I want you to do is you can choose whatever foot you want. I want you to raise it 6 in off the ground like this. You could just imagine that there's like a soda can under your foot. >> Can I lean against something or no? >> No. No, you're not allowed to lean on against anything. So, you're going to bring one foot raised up like so. Arms down at your side. I want you to look at your toes and I want you to count to 30 in this fashion. 1 1,000, 2 1,000, 3 1,000, 4 1,000 and continue on. >> Yes, out loud. >> Okay. Okay. >> Yeah, while looking at your feet, arms down at your side. And like I said, you can choose whichever foot you want. And then I want you to count until I tell you to stop, okay? >> Okay. >> Do you understand? >> I understand. >> All right. You may begin. >> 1 1,000. Okay. 1 1,000, 2 1,000. I don't think I can balance like that. >> Okay. >> 3 1,000, 4 1,000, 5 1,000. 6 1,000. 6 1,000. 7 1,000, 5 1,000. 6 1,000, 7 1,000. >> Okay, you can stop now.
