>An alarming number of people seem to build their intuition about the world from fictional sources, without even realizing it.
A friend of mine had a machete that they destroyed when they took a mighty swing at a tiny tree. You could put your hand around this tree but still, do you expect to chop through a baseball bat with your sword like Conan the Barbarian? Too many films depict unrealistic swordplay.
> You could put your hand around this tree
To be fair, that's entirely reasonable to cut down with a machete. There's a bit of a technique to it and it'll take more than one swing but if you don't have a chainsaw handy a good machete will do the job.
>it'll take more than one swing
That’s the crux of this story. There is an expectation that, if you can chop something down in several swings, then one really big swing will do it, right? No. They don’t make machetes and swords like that, and also you are drastically underestimating the force required, or overestimating your strength, or both.
