For acetaminophen, there's fewer than 500 deaths per year of acute liver failure that they believe is linked to acetaminophen overdose, in the USA.

For water poisoning, the only figure I could find is "a handful of deaths" per year in the USA. Seems that they don't really track that one very closely.

Either way, we're taking about a fraction of a percentage of the population being affected each year. Last I checked the USA had about 335,000,000 people, so 500 people is around 0.000015% of the population? Or one in ~670,000 people are going to die from it.... per year.

If we're going to split hairs over what's more likely or what's statistically possible, I wouldn't bet on either of these. I'm pretty sure you have a better chance of getting hit by lightning or winning the lotto, than being offed by either, less likely if you have an ounce of intelligence to look up the safe daily dose of anything....

It's a dumb argument to make to say what's more likely. Ok, well, how about this, you're more likely to be hit and killed by a motor vehicle.

It doesn't mean anything.
