I mean, this is a bit like Thatcher pretending to only sleep four hours a day; it sounds deeply impressive to stupid people, but would in fact be enormously detrimental to their ability to function properly. I would assume he’s just lying about this, or else including his tweeting habit in ‘work’.

He also believes that he's a "world class Diablo player", which is of course bullshit.

And look what it's done to him. He's a substance addict who can barely form coherent sentences when he speaks. People aren't designed to work like that.
