We have no real way of knowing how many people follow through. Gamblers are, by nature, impulsive and secretive—the ones who leap from a multi-story parking deck after a bad night generally don’t leave suicide notes, while those who do tend to gloss over the reasons for their self-annihilation. Certainly, it’s unlikely that there has ever been an autopsy report that cited “gambling” as a cause of death. Which is not to say, of course, that it wasn’t.
