it's honestly always been insane to me that so many drugs *work at all*. like why is it that these random compounds and byproducts of other biological processes have weird targeted interactions with human biosystems rather than being inert? why the fuck does ibuprofen exist?

it feels like we could very easily have a universe where our systems are much more self-contained and less reactive, which would mean we would have far less control over ourselves than we do. feels like we got lucky af to get access to debug tools
