It's interesting how there's a hint of science here, but so much non-science.
Like, trying to categorize things is a bit scientific. Trying to distinguish between similar but different things is a bit scientific. At the same time, so many of these causes of death are symptoms not causes. And, there are too many cases where they didn't bother to try to find a cause, like the "Planet" cases or "Suddenly". Also, almost all of the deaths are in children / infants, but in those cases they don't try to figure out the cause of death, they just note the age.
