What if I accidentally zapped someone with my stun gun?
On the old “Star Trek” series, Captain Kirk and his crew never left the ship without their trusty phasers. One of the coolest things about these weapons was the stun setting. We’re still a ways off from this futuristic weaponry, but millions of police officers, soldiers and ordinary citizens do carry real-life stun weapons to protect against personal attacks. We tend to think of electricity as a harmful force to our bodies. If lightning strikes you or you stick your finger in an electrical outlet, the current can maim or even kill you. But in smaller doses, electricity is harmless. In fact, it’s one of the most essential elements in your body. You need electricity to do just about anything.
