“The heartbeat is a treasure chest of information…”
Mark Leavitt has a unique perspective in that he is both an engineer and a physician. In his retirement, he is applying his wealth of knowledge to keeping himself healthy.
In this talk, Mark looks at how heart rate variability relates to his willpower. Does he lift more weight when his HRV is high? What happens to his eating habits when his HRV is low? And if the term “heart rate variability” is new to you, Mark gives a lucid explanation.
Also, you will get a glimpse of his amazing customized workstation with pedals to keep him active, a split keyboard on the armrests to keep his knees free and built-in copper strips for measuring HRV. Cue envy.
Historically, the most prevalent self-tracking tool in the home was the scale and the relationship between people and weight is complicated. Akhsar found healthy weight loss to be an emotionally difficult process. His breakthrough came with the Withings smart scale with which he lost 65 pounds in the first year and has kept it off for the last three. In this talk he discusses how the data helped him gain the self control to overcome temptations.

The Beacon Experiments: Low-Energy Bluetooth Devices in Action by Chaise Hocking. There is a lot of interest in using micro-location to support QS projects, with much excitement focused on Bluetooth beacons as a possible solution. If you’ve been curious about how well the fairly well known Estimote and Kontakt beacons work for estimating proximity, this post is for you. ‑Gary
Do-It-Yourself Medical Devices — Technology and Empowerment in American Health Care by Jeremy A. Greene. DIY healthcare technology has existed a lot longer than the devices designed to pair with your smartphone, but the “it” in DIY, as well as whom “yourself” is directed towards, has changed significantly over time. ‑Steven
Boundary Negotiating Artifacts in Personal Informatics: Patient-Provider Collaboration with Patient-Generated Data by Chia-Fang Chung et al. This sensitive research paper explores how self-collected data can be used to support collaboration between people seeking health care and their care providers. Based on surveys and interviews, Chung and her co-authors offer a detailed analytical framework for understanding common tensions and misunderstandings, and give extremely thoughtful suggestions for designers. ‑Gary
‘Superman Memory Crystal’ Could Store Data for 13.8 Billion Years by Stephanie Pappas. It’s probably foolish to get excited by a technology that may never escape the research facility, but I’m excited by the idea anyhow. The challenge of keeping data from degrading is a big one. Libraries burn down. Magnetic tapes disintegrate. Hard drives die suddenly. The idea of storing your data on a glass disc is poetically appealing, but I am surprised to learn of it’s practicality in terms of stability and capacity.‑Steven
The Most Famous Mice in the World Right Now by Steve Hamley. I’ve been following the slow transformation of nutritional science from anti-fat to anti-carb since reading Gary Taubes cover story for the New York Times: “What If It’s All Been A Big Fat Lie?” This week there was a minor chapter in which many media reports used some work by a New Zealand scientist purporting to show that high fat, low carb diets could be bad for your glycemic control after all. The above story by Steve Hamley is the best debunking. ‑Gary
Ann Douglas Details Her Hi-tech Weight Loss Journey by Lauren Pelley. Ann Douglas, an author of books on parenting and pregnancy, lost 135 pounds over two years. She didn’t have one killer device or app, but used a suite of tools that contributed in one way or another. “I had given up all hope of ever losing all this weight,” she says. “If you’re sitting there despairing, wondering how you’re ever going to do anything about your weight problem — I was there too.” ‑Steven
Using Heart Rate Variability to Analyze Stress in Conversation by Paul LaFontaine. “Vapor lock” is Paul’s term for that feeling when you are trying to retrieve something from memory in conversation, but because of the stress of the situation (especially if it is with a boss), you lock up and your recall fails. To better understand this phenomenon and learn how to prevent it, Paul measured his heart rate variability during 154 conversations with bosses and co-workers and discovered that the biggest cause of his “vapor lock” was not what he expected at all. ‑Steven
17 Years of Location Tracking by Stephen Cartwright. Steven has been tracking his latitude, longitude and elevation every hour since 1999. In this talk, Stephen shows how seventeen years of location tracking has given him a wealth of data to explore in the form of three-dimensional data visualization sculptures. He has even brought some of these to QS conferences. They are amazing to behold in person. ‑Steven
Marrying Age: This is when Americans get married by Nathan Yau. This interactive visualization looks at the average marrying age for different demographics. You can’t see the trends over time, but it is interesting, though not wholly surprising, to see smoother distributions for demographics that tend to have more stabile economic situations, like college graduates. (Though I’m not sure if that has more to do with the relative number of people in each group.) ‑Steven
Forget me nots by Lam Thuy Vo. This explores the relationship between a woman and her archive of email exchanges with exes. This visualization above is fairly standard, but the others in the piece are more like tone poems. Appropriate, considering that dives into your archive can leave you swirling in unleashed emotion (Speaking from personal experience here. You would be surprised by how much you can relive your life by looking at old bank statements). ‑Steven
Danielle by Anthony Cerniello. This is a video of a computer generated face that ages over the course of four minutes. The length is interesting in that you can tell that change is occurring, yet it is happening slow enough that it’s hard to see exactly what is changing moment to moment. ‑Steven

The DIY Scientist, the Olympian, and the Mutated Gene by David Epstein. There are several surprising twists in this story of a non-professional scientist named Jill Viles, who made an important discovery about her own rare genetic disorder. What inspired me mostwas Viles’ tenacious reliance on her own capacity to reason, even in the face of skepticism from professionals who had less knowledge (though more confidence) than she did. Eventually, she connects with highly technical scientists whose research direction she influences with her ideas. Epstein got a fantasic quote from one of them when he asked the scientist if this has ever happened before. “In my life, no,” he says. “People from outside coming and giving me hope? New ideas? I have no other example of this kind of thing. You know, maybe it happens once in a scientific life.” I found myself wondering if this kind of thing will be less rare in the future. -Gary
A Drug to Cure Fear by Richard A. Friedman. This article intersects two of my interests that stem from my own self-experimentation. From my stress tracking I realized that many of my reactions in my day-to-day life are influenced by traumatic memories. From my spaced repetition practice I learned how memories can change over time through retrieval and consolidation. A study done in the Netherlands suggests that a memory can be decoupled from an associated fear response by using propranolol which blocks the effects of norepinephrine, a chemical that strengthens connections in the brain. The study has yet to be replicated, but hopefully it will increase our understanding of trauma. -Steven
Internet of Things security is so bad, there’s a search engine for sleeping kids by J.M. Porup. Ever since doing a research project on data flows for our first Quantified Self symposium we’ve had what you might describe as a below average level of confidence in the security and reliability of information traveling outside the immediate context of its collection, now that APIs connect to APIs connecting to yet other APIs. Still, even I was surprised by the recklessness and potential harm described in J.M. Porup’s brief account of a search engine that displays random pictures from internet connected consumer cameras around the world. -Gary
Algae bloom toxin linked to Alzheimer’s, other diseases by Amy Kraft. One consequence of the climate change and the depletion of fish stocks in ocean’s is the increase occurrence of algae blooms. Ethnobotanists found a correlation between algal blooms and neurodegenerative diseases among remote populations in the Pacific. New research suggests that cyanobacteria, the microorganism in these blooms, has a neurotoxin that can cause neurodegenerative precursors that develop. This neurotoxin enters the human food chain as it bioaccumulates in fish and shellfish. -Steven
Glass Half Full Succeeds in Unwinding Upsets by Paul LaFontaine. Most people have moments of irritation or worry throughout the day. Paul wanted to find out what worked better as a response to these moments. Option A was to step back and observe his emotions in a manner similar to that taught by some schools of meditation. Option B was to figure out the source of irritation or concern and think of a positive angle to the situation. What is great about this post is the very simple but illuminating experiment that he devised to explore this question. -Steven
Finding My Optimum Reading Speed by Kyrill Potapov
As an English teacher Kyrill Potapov spends a lot of time working with 12 year old kids who are trying to improve their reading, writing, comprehension, and analytical skills. In this talk, he explores a remarkable method of speed reading, called Spritz, that promises to let you “read Harry Potter in three hours” with full understanding and recall. Could such a promise possibly be true? -Gary

Spurious Correlations by Tyler Vigen. An entertaining collection of unrelated facts that can be correlated with a high degree of confidence. -Steven
Hackers Diet, FIRECalc and weight loss by u/Thebut_. This chart is a mess, but the idea behind it is fascinating. This reddit user was inspired by FIRECalc, a financial tool that “projects your future assets based on historical market data” and tried to apply it to his weight data. Instead of giving a single projection, the tool shows a range of possibilities. This is similar to how Baseball Prospectus’s PECOTA system uses a weighted range of possibilities (probability distribution) rather than a single guess (point estimate) for forecasting a prospect’s future performance. I would like to see more of this kind of thinking applied to personal data. -Steven
Darwin Tunes by Bob MacCallum, Armand Leroi, Matthias Mauch, Steve Welburn, and Carl Bussey. A fascinating project that treats pieces of music like organisms that can mate and reproduce based on listeners’ votes. These audio loops started off as random noise, but as the generations moved into the thousands, the presence of chords and higher order melodies emerged. At this point, there have been over 8700 generations. You can take part yourself! -Steven
Kouris Kalligas, a long time participant and contributor at Quantified Self meetings, is the creator of the very easy to use data aggregation service AddApp. AddApp is an iPhone app that makes it simple to gain insights from data gathered on dozens of different devices. While running his startup, Kouris has also been doing ongoing self-tracking experiments. At QS Europe 2014, he gave a excellent show&tell talk about his sleep, diet, and exercise data. In the talk below, he discusses using mood data in combination with calendar data to reflect on the relationship between emotion, experience, and self-image.

Good tool with too small market can get a second chance – a hardware hack saves Zeo by Portabla Media. A short article on how Philipp Kalwies responded to the demise of Zeo. Since the sensors in the headband need to be replaced every three months and official supplies were dwindling on the secondary market, Philipp began to make his own and hopes to have this resource available to the small group of users who continue to get value from their Zeo devices.

Announcing the 2015 Quantified Self Europe Conference Program
Track HRV, Make a Dashboard, and Have Fun with Fitbit at QSEU15
The 2015 Quantified Self Europe Conference will commence in less than four weeks, bringing together the QS community to share what they’ve been learning with personal data.
Anyone who engages in any sort of self-tracking discovers that the data collected is not a mere recording of some aspect of your life. Rather, engaging with and reflecting on that data can change the way that you relate to an aspect of yourself. Something as simple as getting on a scale each morning can change the way you think about weight. Morris Villarroel has discovered a novel way that this relationship can develop. At this year’s conference, Morris will talk about how using a Narrative camera to keep a visual record of his days, along with detailed notes, has changed his subjective experience of time, “bringing it closer to the present.”
I experienced something similar when I used a spaced repetition system to memorize entries from my daybook. Frequently recalling recent events kept the past distinct and novel. When a month passed, it no longer seemed like a blur, but a container filled with distinct experiences that differentiated itself from any other month.
You can find out more about how Morris gleans value from his lifelog at the 2015 QS Europe Conference. In addition to his show&tell talk, Morris will be leading a breakout discussion on how we can learn more from our lifelogs. We invite you to join us in Amsterdam on September 18th & 19th for two full days of talks, breakout discussions, and working sessions! Early bird tickets are still on sale.
