in 95% better shape than previously suspected

I ran 10 miles with Kushal yesterday. I'm pretty sure that's significantly further than I've ever run before and both Kushal and I were impressed with how well I held up ("annoyingly in shape" were Kushal's words =).
Much to my surprise I woke up this morning feeling perfectly fine with the exception of my knees, which are killing me. I've regretted living on the 5th floor of a walk-up for the last day, let me tell you.
