Ugh, absolutely true. My sneakers got soaked last week and it totally ruined my mood. I've learned to keep a spare pair in my desk drawer, which saves the whole day. That little bit of movement really does keep the commitment from slipping on miserable days.

That part about centripetal force keeping things moving isn't quite right. It's the force that makes things turn, not go in a straight line.

Did I mention that Sapporo ramen shop not in guidebooks, @barnes.brian, because it was in a basement?
