How To Tell If Your Head's About To Blow Up
From the WEEKLY WORLD NEWS, May 24, 1994

MOSCOW - Doctors are blaming a rare electrical imbalance in the brain for the bizarre death of a chess player whose head literally exploded in the middle of a championship game!

No one else was hurt in the fatal explosion but four players and three officials at the Moscow Candidate Masters' Chess Championships were sprayed with blood and brain matter when Nikolai Titov's head suddenly blew apart.

Experts say he suffered from a condition called Hyper-Cerebral Electrosis or HCE. "He was deep in concentration with his eyes focused on the board," says Titov's opponent, Vladimir Dobrynin. "All of a sudden his hands flew to his temples and he screamed in pain.  Everyone looked up from their games, startled by the noise. Then, as if someone had put a bomb in his cranium, his head popped like a firecracker."

Incredibly, Titiov's is not the first case in which a person's head  has spontaneously exploded. Five people are known to have died
of HCE in the last 25 years. The most recent death occurred just three years  ago in 1991, when European psychic Barbara Nicole's skull burst. Miss Nicole's story was reported by newspapers world-wide, including WWN. "HCE is an extremely rare physical imbalance," said Dr. Anatoly Martinenko, famed neurologist and expert on the human brain who  did the autopsy on the brilliant chess expert. "It is a condition in which the circuits of the brain become overloaded by the body's own electricity. The explosions happen during periods of intense mental activity when lots of current is surging through the brain.

Victims are highly intelligent people with great powers of concentration. Both Miss Nicole and Mr. Titov were intense people who tended to keep those cerebral circuits  overloaded. In a way it could be said they were literally too smart for their own good."

Although Dr. Martinenko says there are probably many undiagnosed cases, he hastens to add that very few people will die from HCE. "Most people who have it will never know. At this point, medical science still doesn't know much about HCE. And since fatalities are so rare it will probably be years before research money becomes available."
 

In the meantime, the doctor urges people to take it easy and not think  too hard for long periods of time. "Take frequent relaxation breaks when you're doing things that take lots of mental focus," he recommends.

Although HCE is very rare, it can kill. Dr. Martinenko says knowing you have the condition can greatly improve your odds of surviving it.

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.)
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.)
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.)
4.  Do you spend more than five hours a day reading, balancing your check book, or other thoughtful activity?
(A common symptom of HCE is a tendency to over-use the brain.)
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.)
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.)
7.  Do you tend to analyse yourself too much?
(HCE suffers)

OK this is for real please mail me with your results ok?  Here are mine, and later on I want to publish the results of people who go to my site, seeing how many have to be worried about heir head exploding.

So mine are:

1)  Yes, my head aches when I think too hard.  Not all the time, but enough to make it a yes response.
2)  Yes I always have a faint ringing sound in my ears.
3)  Yes all the time.
4)  Yes I read constantly.  I am always in the middle of a book, sometimes two or three.
5)  Yes, I feel pressure on my temples when I get angry or frustrated.  People sometimes wonder why I massage my temples when I am getting stressed.  Next time I'll just say "my head is about to explode".
6)  Not overly, but I'm not exactly anorexic.  I wouldn't say I crave sugar though.
7)  Absolutely, I think I analyse myself a hell of a lot.  Too much for my own good, at least.

So there you have it.  I scored 6 out of seven, where three out of seven can mean you have HCE.  Yay.  Just wait for my head to explode.

So mail me with your results please, then keep on going.
