Acetone and spontaneous human combustion. Hogwash?
I do not believe acetone, nor any other volatile organic compound, can build up in a human body while alive to allow for ignition, let alone spontaneous combustion. Fat itself, if properly insulated,can oxidize slowly and produce heat to allow for spontaneous ignition. This is why, in days past, painters never piled rags wet with linseed oil. A pile of linseed oil moistened rags will oxidize, exotherm, and catch fire.
The only case of "spontaneous human combustion" I have ever been near was a man who was struck by lightning out of a clear blue sky due to the heat.
Post mortem spontaneous combustion is plausible. In vivo spontaneous combustion does not sound physiologically possible.
