An unusual dance class takes place in Kirkland: one taught by professional dancers and offered free of charge for people with Parkinson's disease and their caregivers. It's one of a small but growing number of such classes worldwide. At this dance class, the students walk in slowly, some rigidly or with a bit of a tremor. They take their places, not at a ballet barre or on the dance floor, but sitting in chairs. As the live music starts, they flutter their fingers like hummingbird wings, point their toes along the ground. Limbs loosen and start to flow. And perhaps something even more important happens: Smiles emerge and laughter erupts.
