The Internet Oracle has pondered your question deeply. Your question was:

> Did you know that if people were 100% graphite reinforced titanium
> steel, they'd be completely immune to gunfire, but they wouldn't be
> able to swim at all?

And in response, thus spake the Oracle:

} Yes, and if people were made out of bread and peanut butter, if you
} toasted them they'd make a nice snack!
}
} And if people were made out of lead, they'd sink when you dropped
} them in the water, and you could make bullets out of them!
}
} And if people were made out of electricity, they could travel over
} power lines, but it would be hard for them to pick anything up!
}
} And if people were made out of cat fur, then some people would be
} violently allergic to themselves, and everyone would shed all over
} the place!
}
} And if people were made out of silicone gel, they'd be kinda squishy!
}
} And if we had some pork, we could make pork 'n beans, if we had
} some beans.
}
} You owe the Oracle some pork 'n beans.
