The Mystery: What Makes Their Blood Boil?

 I was listening to a friend say " I tell you, nosy people just burn me up! They make my blood boil!". 

That made me remember of a strange thing read about not to long ago. It was kind of intriguing. Yet, scary and I wondered could this happen to anyone? The theory or topic of "spontaneous combustion". Spontaneous combustion is when the body apparently just burst in to flames killing the person. There is no known cause, nor has there ever been any "official declaration" of any of the suspected causes of the spontaneous combustion. One reason there has never been a official cause of death accepted in this matter is because scientist are not convinced that it has ever happened. As a scientist if it can not be observed rested and retested under a certain set of criteria, it does not exist. I guess I can see how stringent measures of testing needs to be applied in many things that may be a mystery or unknown. One reason this is important is it is always prudent to separate fact from fiction for important reasons. If this is a real occurrence, my don't we want to prevent it form happening? Of course we do and it my lead us to understanding other things about how the human body works. Before I get to far, let me detail as much as I can, what happens (if it is not self explanatory already). Much of this is observation in the after effects, strangely enough no one has ever witness the begging stages of the occurrences. No one is ever around to see someone "say help me I am on fire". Normally someone may look over and see combustion happening at best. A recent case ( the first documented case goes back 1663 in Paris by a Danish anatomist Thomas Bartholin) happened in Ballybane Galway, Ireland in December 2010. It was the first and only case of its kind. The a young man was found having been burn to death. There was no evidence any flammable fluids and no other flame origin. However, as in all cases the body was burned to ashes and the only area in the siting room where he was the, floor under him and the ceiling about where he was minimally. In all cases the very area where the body sat, stood, or slept was the only area burned. For instance in the earliest case in Paris, the the women's had body had burned to ashes while she slept. Even though her bed was made of straw, no other area around the bed was burned (picture a a burnt chalk  line that outlined the the body). What could have caused this, what thing is so flammable or combustible that the body it's self is burned to ashes but the area around the victim is totally untouched. Even if one were to go with the theory that the body some how burns form its own chemicals, it would not explain the flash burn. It takes 2000 degrees Fahrenheit  to burn the body to ashes. In what area of science has there been a situation where this can occur? One instrument can cause this? Only thing I can think of is a lazor. Although this may sound far fetched, does not chemicals in the body taking on a combustible mix so volatile it it burns  in lightening speed to ashes?  Well, the only thing for sure is that it definitely one of these things that are strange, but interesting, don't you think?
