This neck is yours. If you have not remembered it, and not given it a thought, not given it all its possible movements at least once or twice a day, sometimes not even once a week, some muscle strips are bound to go rusty and let you down, giving you interesting symptoms, giddiness, flashes of light etc. This enables you to wear a special leather-collar round your neck prescribed by top-specialists, as a certificate for your chronic neglect of your machinery.
So with the other parts of your body.
