I am a historian whose specialty is too recent to deal with anything like that (20th century), but also have a friend who, to be generic here, deals with a handful of a few centuries back. She found a baggie of a drug mistakenly stored with a letter in an archive (think 18th century) and on a whim, dipped their pinky into the powder and tried it. They regret that decision, but also, nothing happened:)
EDIT: Historians can be boring, but not always that tame
Most of it was just nice little touches that didn’t change my day much, but the explicit sync in Wayland by also adding the Nvidia 555 driver has really been nice
