By his own reckoning he sleeps for under 5 hours every day. Maybe he's one of the vanishing few who can get by on that amount of sleep (you are not though, so don't try to emulate him), or maybe he's not listing naps he takes throughout the day, or maybe he's just setting himself up for a lifetime of health consequences from prolonged sleep deprivation.
Whichever it is, it's not exactly the sort of routine one should take too much inspiration from for one's own life.
