To the pure geometer the radius of curvature is an incidental characteristic - like the grin of the Cheshire cat. To the physicist it is an indispensable characteristic. It would be going too far to say that to the physicist the cat is merely incidental to the grin. Physics is concerned with interrelatedness such as the interrelatedness of cats and grins. In this case the cat without a grin and the grin without a cat are equally set aside as purely mathematical fantasies.
Well, it so happens that I have had a spinal curvature since I was about thirteen and every once in a while that has given me some trouble, and at that time it began to kick up again. and occasionally I have to get into bed and nurse a severe backache.
My body is damaged from music in two ways.
I have a red irritation in my stomach. It's psychosomatic, caused by all the anger and the screaming. I have scoliosis, where the curvature of your spine is bent, and the weight of my guitar has made it worse. I'm always in pain, and that adds to the anger in our music.
