I can't say that
Susan was particularly excited by my latest leanings toward taking firefighting
class. I believe her immediate response was "I don't want to spend
years taking care of a charred and paralyzed person."
I admitted that
the most mutually respectful approach would be to reach some sort of an
accord, a compromise. I asked first if there was anything that would help
allay her fears.
She answered,
without a moment's pause: "Local mortality data from the past few
years, demonstrating that you'd be at no greater risk than you're already
at, as an EMT."
I had little doubt
that such data, should I locate it, would substantially weaken my case.
But I hope to never shrink from the truth, so I went looking for some
statistics on firefighter deaths. Of course, mortality is less pertinent
than morbidity, since Susan is specifically concerned about me becoming
horrifically disabled. She wouldn't be pleased if I died, either, but
she would stand to collect a decent amount of life insurance, which might
help soften the blow. In any case, I could only find federal records,
covering firefighters' on-the-job mortality through 1994. They were fascinating.
For example, the number one cause of on-the-job death among firefighters?
Heart attack. Burns, which I expected to be the flat-out prime killer,
lagged behind even gunshot wounds. I did not find that last fact to be
particularly reassuring.
I quickly shared
the news about heart attacks with Susan, as it suggested I might be relatively
safe; I don't present as someone likely to be felled by heart attack in
the immediate future. Then I started crunching some numbers. In 1994,
95 firefighters died in the line of duty. Considering that there are around
1,080,000 career and volunteer firefighters in the nation ('96 data),
that doesn't make firefighting seem like an utterly ridiculous risk (.0088%).
But then I flipped the equation over: one in 11,300 firefighters dead
every year. A one in 11,300 chance that it will be you (me). That seems
like a lot. It's probably a greater risk of dying on the job than that
of, say, freelance website designers. Or volunteer EMTs.
Of course, that's
a blatant misuse of math: it presumes that risk is spread evenly throughout
the entire population of firefighters. Instead, I would expect to see
much higher levels of risk in busy urban areas than in rural locations
(or, higher risk in rural areas because they run fewer calls and
are therefore less experienced in a real fire). A more illuminating analysis
would have been number of deaths by number of calls run. If number of
calls accounted for significant variance in the mortality rate, then I
could roughly assess the risk factor based on how many calls I would run.
Of course, some other, unexpected factors might account for substantial
portions of the variance in mortality rates. Wouldn't it be fun to sink
your hands into all that raw data and just dig around in it with a nice,
powerful piece of statistics software? Imagine the little gems of hidden
truth that lie beneath that untouched ground.
I took temporary
solace in the capacity for logic, math, and powerful statistics software
to reduce the ridiculous world to fewer, more manageable components. But
in spite of the numbers, I still feel the strange pull to a shimmering
lure that I first saw in the room with the blinding
smoke. And Susan, though vowing to look at the statistics, is driven
by the same kind of deep emotion that I am, the kind we cannot fully explain
but that shows us something true. We both know the numbers don't matter
too much. We're swiftly moving past the realm of statistics. The conversation
we're having makes math look like pig latin.
