Do the math: if it has happened to 200 people in history, and there is 6 billion people on earth, the chances of it happening to you are around 1 in 30 million. You are substantially more likley to die from a falling coconut (around 75 deaths per year)
Wrong. Not everyone has access to Coconut trees, so you have to take into account the amount of people who have access to Coconut trees. So there's more of a chance to die from falling Coconuts then to self-combust.
