Imagining a fantasy setting where elves, dwarves, orcs and whatnot are just continually baffled by humans eating the most vile toxic things.

Salsa? You mean a mix of a hemolytic poison (onions), a cardiotoxin (tomatoes), and a nerve agent (chili peppers)? Eaten with corn chips dusted with a lethal amount of salt, and washed down with a cup full of neurotoxin (iced tea)?

Stay the fuck away from me because clearly you are the vile spawn of some incomprehensible eldritch god

Anything is poison in a high enough quantity.

We're not fast and don't have a lot of natural weaponry

We are pretty fast compared to a lot of animals, especially when it comes to speed over any significant distance. Only a few other animals (like wolves and horses) can beat us in a long-distance race. And we're especially good at maintaining speed over distance in high temperatures -- as the temperature rises, our advantage there increases.

And having two hands to grab and grapple with (as opposed to only a mouth) is also a pretty rare and special skill in the animal kingdom. Maybe not the most impressive 'natural weaponry', but still quite useful and something to be feared by other animals. Then there's our sheer size -- we're certainly not the biggest ever, but in the grand scheme of things, we're definitely on the larger end of the spectrum, which gives us an advantage over most animals out there.

This isn't exclusive to humans. Tons of animals actively seek out and consume mind altering substances that are generally poisonous. Elephants eat rotting fermenting apples to get drunk, monkeys steal alcoholic drinks from beach resorts, cats inhale cat nip, big cats like lions like to eat psychedelic mushrooms, and dolphins prick themselves with puffer fish poison spines

I mean, there are various other animal species that specialize in eating so much poison that they become poisonous themselves, so we're not very impressive in this regard.

We're not fast but we can run for a long time. Don't have natural weapons but can make them. Then there are people who voted for trump 1-3 times. And other countries that see how the USA is doing and are trying to copy it. I'm not sure where I'm going with this. I hate it here

Don't forget how we've been partying by getting absolutely smashed with a large variety of poisons for fucking millennia. We make alcohol out of plants, honey and even milk.

Isn't there an annual "man vs horse running race" where, once every decade or so, someone actually beats the horse?

Yet, we drink from a mountain stream and we shit ourselves until we dehydrate and die.

Is this about capsaicin? Because that's not a poison by any definition of the word.

That or salt. Which goes well with the stable bond of two of the most reactive substances in the universe, that makes up 90% of our body.

I don't feel alive unless the threat of death is constantly looming over me. That's why I eat shrimp fried ricin.

I can't function without my morning cup of pesticide.

Our superpower is sweating.

we call it a poison, not nature;) no such thing as poisons except what humans use to taxonomize
