3. The "Stomach"
Your stomach is probably one of the most vulnerable parts of your body. There aren't any bones or muscles built to withstand extreme pressure and can result in direct hits to organs. However, we don't actually mean your literal stomach, it's more like your "gut". This weak point is located about two finger widths below your breastbone. If you don't know what a breastbone is, touch the center of your chest. After locating your breastbone, simply feel where the bone and muscle stops and where the fat begins. Just kidding about that fat though, I'm sure your stomach is full of rock-hard muscle.
Then again, maybe you should stop eating pure butter for breakfast. Just a thought.
