Direct current across the brain. Really. I mean, in my younger or attractive days, I fell in for a while with a bunch of kink players who for safety reasons wouldn't even put DC across their et cetera, but other people consider it just fine for their actual brains. Sure.

Ever get that odd morning moment where you're not sure you woke up in the same worldline where you fell asleep? I think this one might be a Cronenberg film, but hey, at least I'm probably not actually in it.

Yeah but you know where a man's brain is.

Interesting. How permanent is the effect? Does it just decrease scores while using it. Or is the decrease in IQ long term.

I don't know, but I would stay away from it. Maybe try exercise instead.

I guess this tech will only be used by a strange niche group that wants the average intelligence of the world to decrease then, huh. Oh well!
