Several people had their names go down in history thanks to their work in the Wild West, including Doc Holliday. He was one of the most dangerous gunmen of the time as he knew his way around the weapon, but would you believe Doc worked as a dentist, too? It turns out he was just 20 years old when he started life as a dentist.
That was until Doc was diagnosed with tuberculosis. The illness was enough to put Doc on another path as he turned to a life of gambling across Arizona. Sadly, the pull of the gun was enough to see Doc return to his roots as he became a gunfighter and a close friend of Wyatt Earp, a famous lawman.
