Phineas Gage is a rail road worker and his job is to blow up rock but, when a early unexpected explosion happens his tamping iron goes straight through his cheek and out his skull damaging his brain, so they took him to the doctor.
But once Phineas and his men got to the doctor he was acting sort of normal he could walk and talk and he wasn't in pain. So the the doctor just bandaged him up. But then a couple of days later he had a high fever and got sick, from a brain infection.
After the accident Phineas was never the same, he would yell foul language, have temper tantrums, and act childish. Also he would refuse to go any where without his tamping iron, and also was fired from working at the raillroad. But Phineas continued to live for another 11 years.
