Because once your central nervous system stops working (your brain) you can no longer function as a normal human being... Putting you in a vegetative state. ( Basically, you become a breathing vegetable on life support machines because your brain can no longer send signals to the rest of your body to proceed with normal tasks.)

Answer 2

Then question of when a human is truly dead have been a source of great discussion for many years. In modern medicine, a patient is considered dead if the brain stops functioning at all, also known as brain death. Brain death is a irreversible end of all brain activity, including involuntary muscle control such as the heart. The heart and organs of a brain dead patient can still kept going using medical apparatuses. If the patient was a organ donor, the body can be kept going until the organs are needed, greatly extending their "expiration date". The first country to accept brain death as a definition of death was Finland in 1971.
