Brett Favre is having a very good season at 39-years-old, but he knows he won't be able to play forever. "At some point, I've got to fall apart," he said Wednesday, smiling. "I'm not going to lie to you. It's like any car; you drive it long enough, it's going to fall apart. You're going to have a flat tire; something's going to happen. But right now, I'm still together."
