Calling Quantified Self! (https://quantifiedself.com/) Damn, that's astonishing. I hope it ends up on youtube: I still watch grainy recordings of HBO from ~1980 for laughs, would love to see what "real" TV with commercials and programming was like over 40+ years.
oldbuzzard · 2013-09-12
I don't follow this area closely myself... but you sound like you are interested in the quantified self movement. Check out http://quantifiedself.com If that looks up your alley, they have meetups every couple of month. See http://www.meetup.com/NYQuantifiedSelf I have no idea of the quality, since I'm out in flyover country but it looks good :) -chris

Personally I found it can help to write down or talk about any emotions which may be present yet currently outside of your scope of perception/awareness. E.g., "based on what happened today, any random person could be excused for feeling ____ or ____." I also found it helpful to reorient my diet toward sweets while processing emotion, foods which my body seems to "request" or crave in order to deal with situations that may pierce the lower portions of Maslow's pyramid. Like you just lost your footing on an important work project and people will be angry, or your stocks took a dive and you panic-sold, etc. By cutting out normal / healthy foods and focusing on indulgent crisis foods first, the overall caloric expenditure can be reduced insofar as crisis foods were what you really wanted to eat, and this direct approach helps to blunt the weight-gain effect of binge eating extra sweets combined with any normal foods outside of that scope. It felt weird at first, but it worked out well, in its strangely logical way. These are just my experiences though, and I really recommend that you keep a log and an open mind and see what you can figure out as you look into this further. I found some helpful mental models related to [0]. Good luck and good on you for raising the question. 0. https://quantifiedself.com/

It's a great post, but to me there's another message that Dustin - understandably - hasn't focused on: "perfect health" is often (usually?) an illusion. Given what I've learned about health in recent years, I can't accept that this guy really was in perfect health; if he was, he wouldn't have suffered a major cardiac arrest while simply jogging on a treadmill. I think it's mostly a failure of modern medicine and modern attitudes towards health that most of us walk around feeling and looking like we're in "perfect" health, only to find all too late that a severe condition was lurking undetected. The answers may lie in fields like Quantified Self [1], or PG's suggestion of Ongoing diagnosis [2]. But whatever the case, we're only just starting to scratch the surface of an area that I think this post demonstrates is hugely important.

I met a woman at the first Quantified Self (http://quantifiedself.com/) conference who was very much into such activities. She wasn't performing the process you described, but she absolutely would be willing. Experimenting with biology in your own homemade closet lab becomes more and more financially feasible everyday.

To be fair, microsoft did kinect, a computer vision product that is in millions of hoees. It wouldn't be hard for google or apple to this but they haven't for some reason. The problem with microsoft has been that is ran it's research wing separate from the business, while google runs research like a business http://cacm.acm.org/magazines/2012/7/151226-googles-hybrid-approach-to… A full shift to the realization that machine learning isn't research and should actually be the majority of what everyone does hasn't sunk in it. The question not be "where can we apply machine learning" but instead "where should machine learning not be applied". This type of thinking should occur even down to the individual person (quantified self) http://quantifiedself.com/ .

It's one of the nicest things to do if you love computers, and great for your health compared with staying indoors. > Could one actually work like this, typing and everything? After my “heart-rate discovery” I decided I had to try it. I thought I’d have to build something myself, but actually one can just buy “walking desks”, and so I did. And after minor modifications, I discovered that I could walk and type perfectly well with it, even for a couple of hours. I was embarrassed I hadn’t figured out such a simple solution 20 years ago. But starting last fall—whenever the weather’s been good—I’ve tried to spend a couple of hours of each day walking outside like this https://writings.stephenwolfram.com/2019/02/seeking-the-productive-lif… https://quantifiedself.com/blog/stephen-wolfram-finds-working-outside-…

That informational abundance or disinformational abundance create a scarcity of attention is hardly novel. Unfortunately most advice tends toward conscious and deliberate rejection of such sources, which continue that assault on attention. As anyone who's implemented an adblocker or similar online annoyance filters is aware, automating the process of distraction rejection is a vastly more effective and less-attention-costly approach. Rather than individually reject cookies, or cookie notices, or trackers, or ads, or various interstitials / "recommendations" / nags / pop-ups / fly-overs, and the like, I've applied and created sets of tools which remove those without my further conscious awareness. Users of PiHole may occasionally check the dashboard blocking statistics and be amazed at how much not only useless but actively counterproductive crud has been avoided. Information overload requires cheap, fast, regret-free rejection tools.[1] I've come to suspect that worldviews and models specifically function in this manner, identifying key information which we should focus on, and costlessly discarding the rest.[2] The article does nod to this briefly, particularly in the note referencing Gigerenzer & Gaissmaier, 2011, but on balance misplaces its emphasis, most especially in its suggestions. Another surprisingly effective tool is randomness, whether in sampling or in decisionmaking directly. Random sampling is a statistical tool for choosing a very small set of…

This is something I think about often when it comes to tools. The idea that Google had all of my location history for the past 8 years means I can see everywhere I've ever gone. I can lookup any email I've ever sent/received. I can look through my browser history for any particular day. With Spotify + Last.fm I can see stats about my listening history, and with Tract.tv I can see my TV/movie watching habits. Strava tracks exercise, and YNAB tracks budgeting/spending. There's an incredible amount of health data from my iPhone + Apple Watch. It's really cool to think that all of this data exists, but I'm not really sure that it's useful. Occasionally I've gone back through my old search history for that one old post that I wanted to re-read, or go through my Spotify listening history to find a song I really enjoyed but forgot the name of, but 99% of that data goes to waste. Quantified Self [0] is an interesting project to me since it seems to make use of data from all of these disparate sources, but I'm still not sure what the outcome of tracking all of this data is. It seems cool but not useful. [0]: https://quantifiedself.com/

Quantified Self is basically about self-tracking and has been around for a while now (I heard about it I think 10+ years ago). https://quantifiedself.com/get-started/

I did something similar back in university after reading about Sen. Bob Graham [0]. For a period of 6 months, I would write down every single action with place and people involved in a small notebook. At the end of the day and the week I would review it. It was really eye opening and allowed me to change some bad habits. [0] I can't remember which article it was, but this one describes his logging activities: http://quantifiedself.com/2009/05/politician-as-self-tracker/

This probably had to do with too little salt consumption. I had to increase my salt intake from 2 to ~5 grams per day. If I don't, I have a mental fog (and cramps and stuff). This talk digs into it a little bit: http://quantifiedself.com/2015/12/effects-year-ketosis-jim-mccarter/

This guy advocates for keto by cutting sugar http://quantifiedself.com/2015/12/effects-year-ketosis-jim-mccarter/ He measures a lot of molecules in his blood streams and noticed reduced inflammation amongts other benefits. I find his short talk nice and detailed although I'm a total newcomer.
tblomseth · 2015-05-04
My piece of advice would be to track any intervention you might choose to implement. Find some indicators that are personal and can tell you whether any given intervention is working or not. I have no personal experience with depression. However, I've used self-tracking to improve my allergies cf. http://quantifiedself.com/2014/03/thomas-christiansen-learning-60000-o… I would also look a bit broader than just your mental state e.g. how are your other bodily functions running. Depressive states might be a signal from your body about something that's amiss in the layers below and/or in your environment.
dlss · 2014-12-29
Ahh, sorry. QS is QuantifiedSelf (for example http://quantifiedself.com/2010/09/seth-roberts-on-arithmetic-and/) I was saying that if you were already tracking yourself, we would be interested in that data as well :) (So for example: meal spacing, vitamin intake, whole food vs refined vitamin intake, exercise types, chlorinated water vs bottled, type and form of fat, soluble vs insoluble fiber intake, whole food fiber vs refined fibers, stress levels, sleep quantity and quality, pet exposure, social exposure, etc) If you're not already logging it (and don't find the idea exciting for other reasons) no sweat... I was just trying to say we'd be very interested in surprising correlations here.

OpenPaths (https://openpaths.cc/) is also a good passive location tracking tool. It's not being actively developed anymore and prone to long loading times, but I've been using it for over a year. Their visualization is pretty good and you can export your data in a variety of formats. Moves (http://moves-app.com) is also good for passive location tracking. Good data export options and some nice mapping integrations with third party services (http://quantifiedself.com/2014/03/map-moves-data/). Disclaimer: Moves is a Facebook entity so caveat emptor

In case you're still checking this thread, I just wanted to let you know how much I appreciated your efforts to educate and correct the record. I know a little about this area, and know enough to see you know more than I do. It's a sad, recent phenomenon of software engineers projecting the epistemic structure they deal with day-to-day onto the medical world. (quick edit) It's profoundly sad to watch http://quantifiedself.com/2010/09/seth-roberts-on-arithmetic-and/ all the way through as a result of this story. It's complicated... maybe it's a failure of medicine, of medical care delivery, education, etc but a room full of educated people laughing off the comments by that person warning of artherosclerosis/stroke and Robert's responses... it's just not a good sign.

I am keeping notes in my own system for >10,000 people that I interact with. My original intention was to automatically generate emails based on combinations of written updates, and I see that your app claims to do a similar email generation task. Can I see some samples of what these emails look like? Also what are the privacy implications of me dumping in all my records and notes? Are these stored locally, or are they transferred to you? Some background on my approach: http://quantifiedself.com/2011/08/bryan-bishop-on-meetlog/

I tracked my learning performance over two years under a range of conditions, including trying a treadmill desk. I found at 1.2mph my error rate (compared to sitting) was 50% less, and I could comfortably study for 2x as long. The trick is to keep the speed quite low, and have your PC at a comfortable position. I now do all my work this way, with an adjustable desk, which I put in sitting position only an hour a day. More details on my experiment are in this talk I gave last year: http://quantifiedself.com/2012/05/jeremy-howard-on-language-acquisitio…
