Yeah, I didn't stick with it (it's really hard to resist the temptation, including temptation to try to be productive at night) but because I tried it I do know now that I'm not a night owl, at all. I'm just a normal person in the West in this century. Which manifests as living like a night owl. I admit my speculation that this explains at least 50% of modern sleep difficulty in developed countries is not based on hard data, but I'd say it's a pretty damn solid hypothesis. Yet everything's all "take magnesium" or "exercise more" or "use redshift" or whatever. Which is probably helpful, but seems like it's ignoring the elephant in the room, which is that we might have too much and too good always-available entertainment (and our lighting situation... after I got used to using candles, which was much faster than I expected, normal electric room lighting was shockingly bright, like I couldn't understand how I thought it was desirable or even OK before).
