I know some people in real life who have battled and survived cancer, so I also know it's not uncommon for their friends/family to shave their heads in show of support.
Anyways, meh...I'm not as into football as I use to be when I was a kid. I used to play it with friends a lot, but slowly grew to dislike it into my teens. However, I do watch games on occasion as well as try to keep up with teams like the Green Bay Packers and the Chicago Bears.
