DISCLAIMER: I AM NOT A FOOTBALL FAN. However, the Mich. - Mich State game makes me want to ask the following: I am 61 years old, 5' 7" tall, 175 lb. I have arthritis in my neck, lower back, and both hips and have had a heart attack. IIRC, I haven't played football since Jr High School in 1966. My question is this; If I suited up and took the place of one of the U or M offensive linemen, would anyone notice the difference?
