I've been working the lung and pericardium meridians a lot this week. We reached a pinnacle this morning working into wheel.
I used to do wheel naturally when I was younger but as I age I find the adage "use it or lose it" to be true. We are as old as our spine is flexible. And the ability to feel and experience our emotions and still open up to life, is the emotional anatomy of the chest. As we mature, we often harden our hearts to these experiences.
