 Going upstairs hits me a little harder than it used to. I've always been a sprint upstairs guy. It doesn't matter the circumstances. I take long strides. If I'm in a crowd and we're a little baby stepping, I'll feel weird on steps. I'm a hit the steps quick guy. So at home, I do that. I just run up my steps, go to bed. I've noticed in the last month or two, the old legs don't turn like they used to on steps. I don't know. I mean, I can still run. I'm not falling over or anything.
