Phineas Gage was a typical train construction worker. He had a semi essential job that requires him to be handy with a tamping iron. If the tamping iron and the gunpowder were used properly, it will create a explosion that creates a large hole.
Phineas leaned slightly over the tamping iron, looking directly at the blasting hole.
The tamping iron slipped from Phineas' hand and went straight through his head. The tamping iron landed 30 feet away.
OH My Lord! What happened?
Phineas was sent to the nearest hospital. Miraculously he was sill alive!
The Tamping rod went through Phineas' left cheek and through the left eye causing the brain to be damaged too.
Even though, Phineas' physical state was healed. He will often get angry or have a moody attitude due to his brain injury.
Even after the gruesome accident. Phineas Gage lived 11 more years after the happening.
