CPU and PH

The CPU is said to be the brain of the computer, and in we humans, it can be said that the brain is our CPU. Both the computer and the CPU won't function if there is no power input. So, the power input can be taken to be the heart of the computer. The heart is the power house of beings. When the power house is faulty, we can be taken as dead just like a computer with no power input. The CPU on its own end has little impact on the power house(PH). When it's faulty, the body won't operate very well. Both aid each other, and when faulty, it can affect one another. What is the essence of this? Your brain and heart should be treated with care, though you can't see them. The things you eat have great effects on this two things. Eat well, live long!
