I understand that sleep is complicated, and also that there's a wide variance in how people respond to sleep (and lack of same).

I wasn't trying to shit on the OP, just that this made it to the front page of HN and has no takeaway from it. All I learned is some 22 year old guy was able to function fine on minimal sleep.

Did I miss something else? I'm genuinely curious because this is actually a subject of great interest to me.
