Its also amazing how many people who use RAID think that RAID-0 is a good idea. Your chances of a array failure are 2^n times greater than with 1 disk where n is the number of disks in the array.
Shouldn't that be 2^(n-1) ? Its actually 2^n compared to RAID 1
Well, it actually has been done before. And quite a long time ago. It is common to use this kind of "mental tricks" for helping people who lost a limb to adapt to the feeling of having something missing.
Sometimes, when you lose a limb (say a hand), the brain re.adapts and the areas that control the feeling of another part of the body expand to the part that controlled the lost hand. Now what happens?
You get touched on certain parts of your face, per example, but you actually feel you're being touched on your missing hand.
So medics use this kind of tricks (sometimes with mirrors) to psychologically make you feel like you had your hand again.. but instead of using a puppet, they used the reflection of your remaining hand

If you have a procedure with 10 parameters, you probably missed some.
