We sit too much in the West. Prolonged sitting stagnates circulation and breath and overloads the lumbar spine. If you are a TV watcher, consider making it a practice to stand up and take deep breaths through the commercial breaks. In your home or work office, create a standing work area. Height adjustable computer stations are becoming more widely available. Set an alarm on your phone or kitchen timer to remind you to change your posture every 20 -30 minutes. It feels good!
