And you don't even need the approval of your banker. No, I'm sorry, that stereo thing is not one of the options. We can't have you going thumpa-thumpa around the neighborhood at 5 a.m., rattling china, waking up dogs, and terrifying newspaper carriers.

And it wouldn't be fair to the roughly 60 or 70 percent of the running population who do just fine with the cheap-o sockliner.
