If you are shot in the head with a paintball will you die?

With the proper safety equipment, and playing with guns that are shooting below the safe 300-350fps range there has never been a death from a paintball headshot. However, if you were to get hit with a gun firing excessivly fast, or get hit in the eye because you weren't wearing a mask there is a risk of death.

Paintball, when played with the proper equipment within safety margins is one of the safest leisure activities in the world.
