The National Safety Council has an interesting page: Odds of Dying.
It lists the odds of dying from various causes and it's interesting to see which activities are more dangerous, vice which activities we think are more dangerous.
For instance, some of the non-gun owners I talk to are deathly afraid of firearms. I'd say irrationally so, but that's me.
Statistically, your odds of dieing in a fall are 1 in 15,614, while your odds of dying in a firearm related accident are 1 in 452,476. In case you were curious, your odds of dying in an assault with firearms are 1 in 25,263.
In other words, if you're going to pick an irrational fear be afraid of the shower.
Obviously, these are just statistics from a broad population, so individual results may vary.
Which is a roundabout way of saying if you're the 1 person who died while a passenger on a streetcar ( odds = 1 in 293,656,842 ) well for you that's a 100% cause of death.
