Good news - NOW

...doctors are optimistic about Rep. Gabrielle Giffords' odds....

Doctors say the bullet traveled the length of the left side of the Arizona congresswoman's brain, entering the back of the skull and exiting the front.

Fortunately, it stayed on one side of her brain, not hitting the so-called "eloquent areas" in the brain's center where such wounds almost always prove fatal.

Importantly, Giffords was responding nonverbally Sunday to simple commands in the emergency room _ things like "squeeze my hand."

That implies "a very high level of functioning in the brain," said Dr. Michael Lemole of Tucson's University Medical Center, Giffords' neurosurgeon.

This does, at the very least, complicate plans for responding to the Zombie apocalypse. If you can shoot someone in the head and not even kill them while they're alive, imagine how much harder it will be when they're dead.

At the very least, I'd say a Glock is contraindicated.
