A little surprising, but only a little. Age isn't a very good measure of wisdom, or even common sense.

I'm reminded of a remark made by the great guitarist Howard Roberts at a seminar I attended in the late 70s. When asked about a certain famous jazz musician's approach to the tune, "Giant Steps," he replied, "Well, you have to have your Shockproof Crap Detector working."
