I did this one after returning from a snowshoe trek up the mountain behind my house. Perhaps it was inspired by skin-absorbed vitamins exuded by the sun, cold air entering my hungry lungs and the type of muscular work that procures endorphins. Perhaps it was produced as an expression of the songs that are welling inside me that are being brought forward in gasping segments. Or, perhaps, it was simply a daily 10 minute exercise in its external form. Your call.
