Push Ups? Really?

While searching the New York Times for information about the beloved sit up and finding zilch, I came across this article about the exalted push up and why it is the enduring symbol of fitness. Could I have chosen my calisthenic as poorly as I chose my college major, retirement plan, and last three cars? Really, I'm wondering, is this a trend?

So anyway, I checked and I can do twelve push ups, girlie style. Tomorrow, though, I now have confidence, I'll do thirteen.
