An unusually bitingly cold wind was blowing off the water as I walked back to my apartment building after an energetic dance lesson. It was freezing outside and entering the warm lobby, I could almost feel the synovial fluid in my joints thawing like congealed olive oil taken out of the refrigerator. That’s also how I feel sometimes, getting out of bed after a good night’s sleep. I bounce out of bed full of energy and raring to go but while my muscles and joints are warming up, my first few steps resemble the Tin Man.  Except on the mornings after the days that I have three hours of dance and an hour of fast walking. Next morning I wake with no stiffness in my legs. The more you move the more you can move.,
