The brain is responsible for every other organ in the body. If the brain is degenerated, it means it can't successfully control the other organs in the body. With a degenerated brain, life expectancy is way lower than with normal brain. When you see Judeo-Satanists living long, it means they have spent a lot of money on organ transplants, or even transfusions of child blood, or whatever shit they are taking on order to not die early.
