Bullet proof vests provide a protective layer between the bullet and your favourite, life saving organs, but humans already come with their own natural protective layer: Adipose tissue (that's fat to me and you). Considering you can actively increase the amount of adipose tissue you have through the judicial application of donuts, how much would it theoretically take to stop a bullet?
Luckily, the Cavendish Laboratory at the University of Cambridge, along with the Naked Scientists, have run the experiment and have a result for us. To mimic the fat, the scientists used ballistic gel and fired a bullet into it at supersonic speeds.
Unfortunately, they discovered that you would probably need about 72cm of fat to stop a speeding bullet. So, you might not die from a bullet wound, but it might just be the heart attack that gets you.
