Sitting is the New Smoking
Posture is simply the response of our bodies to gravity, the moment to moment conversation our bodies have with gravity. This conversation begins at birth, and continues as babies first lift their head, then creep, then crawl, then toddle and finally stand. Throughout this awakening of the body the spine is adapting to gravity, developing the normal curves in the lower back, thorax and neck that allow for perfectly balanced, calorically efficient standing and sitting. Simultaneously the body is also developing spinal reflexes that facilitate efficient posture, reflexes that adjust the spine in real time to assure balanced, stable posture. Importantly, these reflexes also allow the spine to adjust on the fly to surprises that might cause a fall if not compensated for.
