 And also joining us is journalist Johan Hari, who's author of many books, including Stolen Focus, Why You Can't Pay Attention, and How to Think Deeply. Again, Johan Hari, welcome to you. Hey, Jeremy. I should just warn everyone. It is 2 a.m. in London, and I've drunk enough caffeine to kill a whole field of cows. It is possible I will die during this interview. I'm glad my last words will be recorded for posterity.
