a genuinely sinister drug

I liked this (via):

Although technically speaking releasing testosterone precursors on the world’s trading floors to try to rally valuations wasn’t criminal as such, the affected traders lobbied to declare it illegal. But governments liked the idea too much, and oxygen masks were forbidden.

(Electronic traders were of course immune, but they knew floor traders would be bullish and that was enough for them to become so, too. Soon there was no need to spend on the chemicals anymore.)

I think it was at last 3GSM I suddenly thought of the possibility of someone inventing a sales drug - a pill that would fill you with energy and induce repetitive behaviour (always be closing, right?), whilst at the same time making you hypersensitive to others' emotions...but completely indifferent to them, and also completely incurious about what you were doing. The street, or the Street, would probably call it Animal Spirit.

And then I jumped under a tram. No. In fact I thought someone should write the book before someone actually invented it, with whatever nightmarish meat-hook consequences that would have. Then I forgot all about it at wheels-up, until now, when the approach of the next 3GSM brought it slithering to mind.
