From Reuters: The spell cast by the latest Harry Potter book may have an unintended side effect. A Washington doctor warned that he has seen three children complain of headaches caused by the physical stress of relentlessly plowing through the epic 870-page adventure.

Call them Hogwarts headaches, named after the wizard school that Harry attends.

Dr. Howard Bennett of George Washington University Medical Center wrote in a letter to this week's New England Journal of Medicine that the three children, ages 8 to 10, experienced a dull headache for two or three days.

Gee, 'course they got them headaches from those damn 'arry Potter books. They' never complained before, now did they?

As a kid I've used to read books for many hours a day with no ill effects, other than having no friends and being fat. Could it be that those kids never got any headaches because they have never read a fucking book?

I'm waiting for the parents to sue Mrs. Rowling.
