What zodiac sign has the lowest suicide rate?

Well there isn't any scientific data on this, per se. The problem is that science doesn't believe in Astrology, but auto-insurance does! There have been numerous studies which indicate that Scorpio is the least likely to die (or even be involved in) a fatal automobile accident. This is surprising, considering Astrology says ScorpiOS are prone to alcohol abuse and risk taking. Come to think of it, this data is an indictment of the M.A.D.D. syndicate as well. Anyway, dying in automobile accidents is a risky behavior, and suicide is often associated with that. So, based on the items I laid out here, I would assume ScorpiOS are the lowest rate, given their aversion to truly risky behavior which has been studied and documented.
