Pencil in the Head...?

According to the Associated Press on Monday August 6, 2007 - A German woman, Margret Wegner became free from the root of many headaches over the past 55 years. Wegner is a 59 year old lady living in Germany who had a pencil removed out of her head after being in her head for 55 years. When she was four, Margret was carrying the pencil in her hand when she fell and the pencil went through her skin and "disappeared" into her head. Luckily the pencil missed vital parts of her brain although it is believed that the pencil was the root of many headaches and mental pain. When this occurred 55 years ago, no one was willing to operated on her brain although due to great advancements in technology doctors have become able to remove it.
The majority of the pencil, some 8 cm (3.1 inches) long, was taken out in an operation at a private Berlin clinic, but the 2 cm tip had grown in so firmly that it was impossible to remove.
