Every year I tune in expecting one of the N9 to be sick as a dog, since let's face it - stuff goes around this time of year and folks get sick. But as far as I remember I don't think it's every happened, or at least not in a way that the viewer could perceive (coughing, nose blowing).
I guess they just do Purell Silkwood showers in the week leading up to it. I know that's what I'd do, although in the interest of full disclosure.........
