“Text neck”, the abnormal force on the cervical spine while tilting the head as we scroll on a smartphone, may not be the worst consequence. Normally, while breathing, we do so deeply from the diaphragm, but when holding a device with a bent neck, we tend to breathe shallowly. Over decades, this could damage lungs. Hopefully I am wrong (1 February, p 27).
