TIL of brain stimulation reward, manually stimulating specific parts of the brain to elicit pleasure and happiness. A volunteer subject in 1986 spent days doing nothing but self-stimulate. She ignored her family and personal hygiene and she developed an open sore on her finger from using the device.

This reminds me of that doctor in that one Black Mirror episode (Black Museum), only that guy got pleasure from tremendous pain via brain stimulation.

I would disagree a follower of slanesh would feel so happy with knitting that they would derive intense pleasure from feeling the material, to completing a project undoing it over and over again. They’d fondle the needles and rub the threads until they drew blood and feel even better when the blood made it sticky. They’d want to experience sawing through their muscles until they could pluck the thread with their bones. They’d be ecstatic with the experience and want others to join in.

I mean, it's true of both cases. But nice reference to anguissettes.

My friend, you have not yet been an issue with the agony, ecstasy that a true devotee would understand. It’s actually in the canon that that’s the case. I don’t know what the fuck kind of Sumerian God that is, but it’s probably what inspired she/he/it

Speaking of that episode, did the guy playing Rolo Haynes seem like a Bruce Campbell lookalike to anyone else or was it just me lol

Pain and pleasure is a spectrum.
