Go and sit in a quiet place.
No music, no TV, no voices, not even the sound of birds singing.
Sit upright, straight back, head balanced perfectly on the supporting vertebrae.
Shut your eyes.
Now turn your head slowly to the left, then slowly to the right.
If you listen carefully while you do this, you'll be able to hear the very slight grating noise produced by the degenerating load-bearing surfaces of your ageing vertebrae and supposedly lubricating cartilage.
That grating noise is the sound of old age
Sometimes life's a real pisser.
