@posture.app: Stand with your back to a wall: heels, hips and shoulders touching. Does the back of your head touch too, with your eyes level? If there is a gap, glide your head straight back. Do not tip your chin up, and do not force it; stop if anything hurts. Save this and try it tonight. Search "Posture: Scan & Fix Slouch" on the App Store. #posture #walltest #forwardhead #posturecheck
