I'm making the transition from nerd to jock. It doesn't surprise me that you don't believe me, which is why I'm presenting evidence!
A couple of years ago, I went to Microsoft Tech-Ed and got 14 t-shirts! A couple were medium-sized and so I gave them away, but I'm pretty sure I kept the rest. And added them to my collection of IBM t-shirts. That is to say, virtually all my t-shirts were related to technology companies. My mom tried her best to counteract this by buying me the occasional t-shirt that she found hilarious, but I don't think I'd go so far as to say that they made me less nerdy.
Recently, however, I've been running [I didn't end up running in this 5K due to food poisoning] some 5Ks and other benefit things that give out t-shirts. Thus, my t-shirt wardrobe is gradually transitioning from technology t-shirts to running t-shirts. Plus, I wrote recently about football, though admittedly I was on the outside of the conversation. Still, incontrovertible evidence that I am changing from being a nerd to being a jock!
To be fair, there is some evidence that this is a very slow process in its earliest stages. But only a little bit of evidence, really. And I suppose that this post kind of contradicts itself. And all but one of the fitness-related tags below are new....
