How do we spend our time?
Jared Chung was curious about how he was spending his days after he transitioned from his role as a consultant into his new startup venture. Inspired by pervious Quantified Self talks he decided to start tracking his time and his daily activities (work, exercise, sleep, etc.) using Google Calendar. This ongoing tracking project has helped him identify how he spends his day and how that compares to his planned activities. Watch this great talk filmed at the QS Boston Meetup to learn more about what Jared learned and how you can get started tracking your time
Awais Hussain is a student at Harvard, and he found himself asking the age-old question, “Where does my time go?” Using his online calendar Awais started tracking his daily activities. This tracking has given him some interesting insights into how he really works and accomplishes tasks. Watch this great talk to hear more about what Awais learned by keeping track of his time.

At a recent QS meetup in Boston, Gary shares a few quick insights on the challenges of restarting a tracking practice once you’ve stopped, gamification vs. motivation, and his experience of meditation. Check out the video below, as well as a more detailed discussion about his meditation practice.
Ryan Hagen is a doctoral student in clinical psychology who’s terrified of people getting therapy through Siri. That said, for his PhD project he was inspired to extend the work of Sandy Pentland and ginger.io correlating people’s passive smartphone behavior data with anxiety and depression. In the video below, Ryan explains his current three-month study, which you can check out or join here. (Filmed by the Boston QS Show&Tell meetup group.)
Carl Valle, track and field coach to elite athletes, believes that the three categories of things to measure for optimal health are activity, biochemistry, and cardiology. In the video below, he walks through his favorite tips for each of these. (Filmed by the Boston QS Show&Tell meetup group.)
Catherine Kerr does brain science related to mindfulness at Brown University Medical School. She points out that mindfulness traditions ask practitioners to simply focus closely on body sensations in order to bring attention to the present moment. Why does this help with depression? In the video below, Catherine explains some of her magnetoencephalopathy (MEG) research to answer this question, and suggests that detecting cortical changes may be one of the earliest, instinctive QS-related forms of self-awareness. (Filmed by the Boston QS Show&Tell meetup group.)
Alan Bachers is an expert in neurofeedback training, which he comfortingly describes as helping the brain learn how to calibrate itself. He suggests that this training accelerates the process of getting into meditative or other desirable mental states, and can possibly help a medicated brain learn to function without medication. In the video below, he does a fascinating live demonstration of the NeurOptimal system on an audience member, with on-screen visualizations of the volunteer’s brain activity. I’d love to see how my brain looks with this tool! (Filmed by the Boston QS Show&Tell meetup group.)
Douglas Mason didn’t know who the Beatles were until he went to grad school. As a classically trained musician, he was blown away when he saw their unique chord choices. He started to investigate why the Beatles’ music sounded so good. Douglas created a shorthand musical notation to represent songs as strings and analyze things like melody, time signatures, chord changes, and lyrics. He describes his project and what he has learned in the video below. (Filmed by the Boston QS Show&Tell meetup group.)
QS Boston Meetup #5 was held on Wednesday on the topic “The Science of Sleep,” a subject that comes up here regularly. The event was major success and, to my mind, demonstrated powerfully the potential of the self-experimentation movement and the exceptional people making it happen. Here is a brief recap of the evening, with my comments on what was discussed. A big thanks to Zeo for their generous support of the meeting, QS Boston leader Michael Nagle, and sprout for hosting the event.
Experiment-in-action: A participatory Zeo sleep trial
Michael put the theme into action uniquely by arranging for a free 30-day trial of Zeo sleep sensors to any members who were interested in experimenting with it and willing to give a short presentation about their results. Over a dozen people participated, and the talks were a treat that stimulated lots of discussion. I thought this was an excellent use of the impressive members of this community, as the talks demonstrated.
Zeo research scientist Steve Fabregas kicked off the meetup by explaining the complex mechanisms of sleep, and the challenges of creating a consumer tool that balances invasiveness, fidelity, and ease of use. He talked about Zeo’s initial focus (managing Sleep inertia by waking you up strategically), which – in prime startup fashion – developed into the final product. Steve also gave a rundown of the device’s performance, including the neural network-based algorithm that infers sleep states from the noisy raw data, something he said that even humans have trouble with. There were lots of questions afterward, including about their API and variations in data based on age and gender. All in all, a great talk.
Sanjiv started out the sleep trial presentations with a lively talk about the many experiments he’s done to improve his sleep, including a pitch-black room, ear plugs, and no alcohol or caffeine. But the biggest surprise (to him and us) was his discovery of how a particular color of yellow glasses, worn three hours before bed, helped his sleep dramatically. This is apparently based on research into the sleep-disturbing frequencies of artificial light. He shared how wearing these also helped reduce jet lag. The talk was a hit, with folks clamoring to know where to get the glasses. I found this page helpful in understanding the science. (An aside: If you’re interested in trying these out in a group experiment, please let me know. I am definitely going to test them.)
Adriel studied the impact on weather and his sleep (via the Zeo’s calculated ZQ) by recording things like temperature, dew point, and air pressure. He concluded that there’s a possible connection between sleep and changes in those measures, but he said he needs more time and data. Audience questions were about measuring inside vs. outside conditions, sunrise and sunset times, and cloudiness.
Susan tested the effect of colored lights (green and purple) on sleep. Her conclusion was that there was no impact. As a surprise, though, she made a discovery about a the side-effects of a particular medication: none! This is a fine example of what I call the serendipity of experimentation.
Eric tried a novel application of the Zeo: Testing it during the day. His surprise: The device mistakenly thought he was asleep a good portion of his day. He got chuckles reflecting on Matrix-like metaphysical implications, such as “Am I really awake?” and “Am I a bizarre case?” His results kicked off a useful discussion about the Zeo’s algorithms and the difficulty of inferring state. Essentially, the device’s programming is trained on a particular set of individuals’ data, and is designed to be used at night. Fortunately, the consensus was that Eric is not abnormal.
Jacqueline finished up the participatory talks with her experiment to test whether she can sleep anywhere. Her baseline was two weeks sleeping in her bed, followed by couch then floor sleep. Her conclusion was that her sleep venue didn’t seem to matter. One reason I liked Jacqueline’s experiment is that, like many experiments, surprises are so rich and satisfying. Think bread mould. She said more data was needed, along with more controls. Sadly, she wondered whether her expensive mattress was worth it. Look for it on eBay.
Matt Bianchi, a sleep doctor at Mass General, finished out the meetup with a discussion of the science and practice of researching sleep. Pictures and a description of what what a sleep lab is like brought home the point that what is measured there is not “normal” sleep: 40 minutes of setup and attaching electrodes, 200′ of wires, and constant video and audio monitoring make for a novel $2,000 night. He said these labs give valuable information about disorders like sleep apnea, and at the same time, what matters at the end of the day is finding something that works for individuals. Given the multitude of contributing factors (he listed over a dozen, like medications, health, stress, anxiety, caffeine, exercise, sex, and light), trying things out for yourself is crucial. He also talked about the difficulties of measuring sleep, for example the unreliability of self-reported information. This made me wonder about the limitations of what we can realistically monitor about ourselves. Clearly tools like Zeo can play an important role. Questions to him included how to be a wake more (a member said “I’m willing to be tired, but not to die sooner,”) to which he replied that the number of hours of sleep each of us needs varies widely. (The eight hour guideline is apparently “junk.”)
Matt’s talk brought up a discussion around the relative value of exploring small effects. The thought is that we should look for simple changes that have big results, i.e., the low hanging fruit. A heuristic suggested was if, after 5-10 days, you’re not seeing a result, then move on to something else. A related rule might be that the more subtle the data, the more data points you need. I’d love to have a discussion about that idea, because some things require more time to manifest. (I explored some of this in my post Designing good experiments: Some mistakes and lessons.)
Finally, Matt highlighted the importance of self-experimentation. The point was that large trials result in learning what works for groups of people, but the ultimate test is what works for us individually. (He called this “individualizing medicine.”) This struck a chord in me, because the enormous potential of personal experimenting is exactly what’s so exciting about the work we’re all doing here. All in all, a great meetup.
