 Well, if I ride past you, I might think about, there's my halt. To rain back or to back up, don't be leaning back, because if you're doing that, you're driving their back down. He needs to lift his back to back up. So in a rain back, I want you to think about sitting tall and I push my seat back against the cantile. Imagine this, you're getting out of your chair at the kitchen table and you wanna slide the chair back to get off the chair. When you slide a chair back, do you do this? To slide a chair back? No, you'd flip over backwards. What do you do when you slide your chair back? You sit up and you push your seat back. He feels that on his back. Now, if I wanna go forward, I sit up and I swing my seat forward.
