My personal opinion and experience indicates to me that there are a whole lot of people who are simply unable to handle quietness. They get up in the morning and the first thing they do is turn on the TV. If they're in the car they turn gotta have music or talk radio. If they could find a way to have a television on their push carts they would. It's not the music, for them - it's the noise.
Charles is 6'6".
We don't know how side by side they are and also if Barkley is standing on ground slightly higher. It looks like the top of Phil's head reaches around ear level of barkley. He could be 6'3" with shoes on.
