Life would be very boring if we all agreed all the time. I'm open to changing my mind. Give me some evidence. I offer the following in support of my assertion:
Lie flat on your back on the floor with knees bent up so that your feet are flat on the floor too. Place your elbows on your torso like you do in your golf swing. Now roll your knees to the left. Do your arms move? Mine don't, but my hips do. But I am rather tall for my age.
