I brought my own CD since the instruction sheet said I could. What it didn't say was just how loud the magnetic noises would be, reducing Bach to tinny sounds far, far away in the stratosphere. A different coloured liquid was injected in my arm - the bottle is purely imaginary but I can't swear that the ancient Egyptian character was not there, performing an ancient ritual designed to remind me of where I came from and reassuring me that it's not time to go yet.
Why don't they employ some ordinary DIY enthusiasts to solve the noise problem in these state-of-the-art scanners? I'm sure they'd come up with something - wouldn't you, if you lived next door to one of these with no chance of moving elsewhere? Pure technology, like pure magic and pure art, often lacks common sense. Big noise is big problem to most humans and so are confined claustrophobic spaces. You need a touch of the common to deal with human problems.
