Ouch.

My head is about to explode. Seriously.

I know you all tend to feel I may be a little teensy bit overly melodramatic, but it really can happen:

Please take note of this line: Victims are highly intelligent people with great powers of concentration.

Also, this one: ...the doctor urges people to take it easy and not think too hard for long periods of time.

As to the test:

A "yes" answer to any three of the following seven questions could mean that you have HCE:

1. Does your head sometimes ache when you think too hard? (Head pain can indicate overloaded brain circuits.) YES
2. Do you ever hear a faint ringing or humming sound in your ears? (It could be the sound of electricity in the skull cavity.) OCCASIONALLY
3. Do you sometimes find yourself unable to get a thought out of your head? (This is a possible sign of too much electrical activity in the cerebral cortex.) OCCASIONALLY
4. Do you spend more than five hours a day reading, balancing your checkbook, or other thoughtful activity? (A common symptom of HCE is a tendency to over-use the brain.) YES
5. When you get angry or frustrated do you feel pressure in your temples? (Friends of people who died of HCE say the victims often complained of head pressure in times of strong emotion.) OCCASIONALLY
6. Do you ever overeat on ice cream, doughnuts and other sweets? (A craving for sugar is typical of people with too much electrical pressure in the cranium.) YES
7. Do you tend to analyze yourself too much? (HCE sufferers are often introspective, "over-thinking" their lives.) YES

As I said, my head is about to explode. I wonder if I can get a nurse's pass from my anatomy exam for that?
