Every time the matter of McCain’s age is raised, I yawn. I know it’s an aspect of the candidate that is worthy of some discussion, especially in the context of what is possibly the hardest, most taxing job in the world. At the same time, I have trouble fretting too much about the Senator’s almost-72 years. My apathy is perhaps best explained by what Groucho Marx once said: “Age is not a particularly interesting subject. Anyone can get old. All you have to do is live long enough.”
