I looked into becoming a volunteer firefighter after I got out of the Marines, but honestly the extremely long training required and the extremely high potential for PTSD from fire calls gone bad put me off from it.
One of my first stories was with some local firefighters that responded to a car wreck.
When they got there, there was a woman trapped in the wreck.
Then it caught fire. There was nothing they could do but watch the woman burn to death.
Decided then and there that firefighting wasn't in the cards for me.
I was always good with computers. Even when I was writing, I ended up installing a computer network for the local newspaper. Eventually I just gave up and went into computers full-time.
