The ideal of anarchism is a society in which all individuals can do whatever they choose, except interfere with the ability of other individuals to do what they choose. This ideal is called anarchy, from the Greek anarchia, meaning absence of government.ut anarchy is not perfect freedom. It is only the absence of government, or coercive establishments. To show that perfect freedom is impossible is not to argue against anarchism, but simply to provide an instance of the general truth that nothing is perfect.
Cerebral spinal fluid (CSF) collection. Cerebrospinal fluid (CSF) collection is a test to look at the fluid that surrounds the brain and spinal cord. CSF acts as a cushion, protecting the brain and spine from injury. The fluid is normally clear. It has the same consistency as water. The test is also used to measure pressure in the spinal fluid.
A CSF leak is an escape of the fluid that surrounds the brain and spinal cord. Any tear or hole in the membrane that surrounds the brain and spinal cord (dura) can allow the fluid that surrounds those organs to leak. This fluid is called the cerebrospinal fluid (CSF). When it leaks out, the pressure around the brain and spinal cord drops. Sometimes, no cause can be found. This is called a spontaneous CSF leak.
