I have a headache. It gets a 2.
Headaches suck; sometimes your head hurts in the back, and sometimes it hurts at the temples. Once in a while it even hurts in the very front.
If you have a great deal of stress or tension you may develop a headache. If you hit yourself in the head with a hammer you might also develop a headache.
Sometimes a headache can really make you feel miserable emotionally, especially if you do have stress, or you are upset for other personal reasons.
There is one good thing about having a headache. If you have a headache, it means you are still alive. Only living people can feel pain; dead ones don’t mind so much. That is the only reason it gets a 2 and not a 1.
Here is an article from Wikipedia, written by people who are probably much smarter than me (and probably much smarter than you if you are reading this blog) about headaches.
