Bear Durability #1

But just shooting the bear may not be enough to stop the attack. Bears are tough with heavy muscle and hide and very strong, thick bones. So, the first challenge is for the bullet to penetrate deeply enough to get to vital organs which, when damaged sufficiently, will cause the animal to stop the attack immediately. However, even if the heart or lungs are destroyed, the bear may still have enough oxygen and blood in its system to carry out the attack and kill the victim. Sure, the bear may die, but not before the victim is dead.
