    So I thought I'd make a list of open questions that bug me occasionally ( http://www.gwern.net/Notes#open-questions … ), and lacking any better idea, grepped my logs for "weird". Many of the hits turn out, lacking context, to be deliciously weird. ^_^pic.twitter.com/IPFLDVYHu3

        Another odd observation: programmers love writing at night; evening 'owls' are smarter & more creative than morning 'larks'; so why do available anecdotes & surveys show that writing in the morning seems to better? https://www.gwern.net/Morning-writing  @robinhanson

        Also running a Google Surveys survey to try to measure how many owls report improvements from writing in the morning, apparently contrary to chronotype. (I love using Google Surveys for anything I can fit into a single question and it baffles me so few people use it.)

        "Does moderate alcohol consumption have health benefits, or not?" The consensus seems to be no overall benefits.https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(18)31310-2/fulltext …

        They still find J-curves.

        Not in the overall weighted relative risk.

        Which is of no relevance to the intractable moderate-drinking debate, as all parties involved agreed many decades ago that large amounts of drinking hurt and alcoholism is rampant globally...

        I'm talking about moderate drinking "In estimating the weighted relative risk curve, we found that consuming zero (95% UI 0·0–0·8) standard drinks daily minimised the overall risk of all health loss" https://els-jbs-prod-cdn.literatumonline.com/cms/attachment/ed9c740a-8a3f-4549-8b35-b4ae2747f181/gr5.jpg …

        Ah. Their curve looks still consistent with benefit from moderate drinking (their graphic choices make it hard to see a few drinks a week), and regardless, correlational method can never answer the question & other analytic choices/datasets show different results; hence, debate.

        "Brazilian Jiu-Jitsu" - I think you should only be comparing to grappling and ground fighting techniques.

        Kickboxing+BJJ aside, I'm not sure how much that even mattered. The Gracies stomped everyone regardless. What I'm puzzled by is this vast inefficiency in an endeavour which should've been long since 'solved'.

        Ground fighting leaves you very vulnerable in scenarios where many people are involved. But yes, it's strange to me also why many traditional fighting techniques were so inefficient until the UFC appeared.

        I mean, it's not like people didn't have very strong incentives to get it right or fast feedback loops to test methods!

        "nicotine is one of the best stimulants on the market: legal, cheap, effective, relatively safe, half-life much less than 6 hours." What about the dependence?

        Replying to @LechMazur

        Minimal in never-smokers, less than, say, caffeine. At least, for patches/gum/lozenges... Vaping is such a fast delivery method and typically used so frequently it may be much more addictive. (I've never vaped and I don't intend to start.)

        Yeah, there is very little about nicotine dependnce among never-smokers. But this is interesting: "The other half, however, chose the placebo, often explaining that the nicotine pill [...] made them feel light-headed, dizzy or sick."https://www.hopkinsmedicine.org/news/media/releases/study_with_never_smokers_sheds_light_on_the_earliest_stages_of_nicotine_dependence …

        Yeah, I've seen that. I've wondered if it's a sensitive/dose issue. The symptoms sound like the usual ones when you take a new stimulant and dose too high. And you never respond to a stimulant more than the first time.

        That's where I got the idea, seeing yours & the HN discussion. It occurred to me that instead of randomly musing about these anomalies every once in a while on Twitter/Reddit/IRC, I could make a list like yours and at least I would stop repeating myself so much!

        Thanks. Indentation problem (not enough spaces), probably due to a long-standing bug about HTML comments in markdown-mode...
