The electromagnetic waves generated by cell phones are shown to prevent Alzheimer's disease in lab mice.

For two hours a day, researchers exposed 96 rodents -- about half of which had been genetically altered to develop Alzheimer's-like symptoms -- to radiation emitted by a typical cell phone. After nine months of this treatment, the scientists tested the mice on their memory. Following the exposure, the lab animals predisposed to developing Alzheimer's were less likely to show signs of the brain disease when compared to vulnerable mice that were not exposed to radiation. In addition, the memories of normal mice also improved.

The researchers warn that these surprising benefits to cell phone use may not apply to humans, who have much thicker skulls than mice.

Anyway, it's 2010. Who in the name of nimble fingers and Bluetooth is still pressing their cell phone against their head for two hours a day?
