You're very unlikely to die from an earthquake. Chances are only 1 in 117,000. Hot weather is significantly more dangerous -- and will become yet more dangerous than that -- as it already kills 1 in 13,000. Motorcycle accidents take out 1 in 1,020, and my understanding is that when you restrict that to the motorcycling population, it's something like 1 in 1. Cars will do in 1 in 84 of us, and strokes 1 in 24. And then there's heart disease, which will bury an impressive 1 in 5. Where are all these grim numbers coming from, you might ask? Why, the death spiral, which shows this graphically. Sadly, it misses a few key causes of death. Terrorism and airplane crashes would've been nice to include, if only to show how few they really kill. And what of the coming robot menace?
