<human>: Give me the gist of the text in a nutshell

So this actually happened to my great uncle quite a while ago, but it is a great story and I thought you guys would like it.

So Frank was a dairy farmer, and every day he would go out at 4 in the morning to milk his cows. He had a milking machine so that he didn't have to do it by hand.

So this particular morning he went up to the bails with his kerosene lamp to see, and his fuel to fill up the milking machine. As he held the lamp in one hand and poured the petrol with the other he had a bit of an accident, as you can imagine.

His wife woke up to hear chilling screams and a huge vertical flame running around the yard. She managed to put the fire out and race him to the hospital, but not before he was scarred all over his body including losing his ears, most of his nose, and five fingers.

Here's the great part though. Just a week before the accident, a traveling minister passed through the town and had been telling Frank that he should get life insurance. Frank couldn't afford it, so the minister paid for Frank's first insurance premium. 

Now being an illiterate farmer who can no longer work with his hands, you would think that there wouldn't be much in the way of jobs for Frank to do. In the end he made a killing from selling insurance, he would tell his story to all of the farmers in the area and they would join up straight away.
<bot>: my great uncle set himself on fire and was severely burnt a week after getting life insurance. He then earnt a killing selling life insurance by telling his story.
