You might not be able to see what this picture is and know
what this picture is about. Let me tell you what it is, this is a picture of the bottom part of a brain. It is a
brain of a smoker. When people smoke it can damage the brain. In the picture above you can see that it is all red. Why?
Because when you smoke a lot, the arteries get cloged up and the blood won't flow through to some places in the body.
If the blood can't reach the heart this will cause a heart attack. Also, if the blood can't reach a part
of the brain you will lose that part: for example if the part where it controls the speech you will lose the sense
of talking. If the part is a part of life you will die. This is called a blood clot.
