An informational vector infographic titled "THE CHRONOBIOLOGY DIMENSION: BIOLOGICAL TIMING MATTERS." It uses charts and diagrams to compare the body's response to an identical meal at 8:00 AM versus 8:00 PM. A central human figure illustrates internal biological clocks. Morning meal timing shows "Optimal Metabolic Timing" with a smooth glucose curve. Evening meal timing shows "Circadian Mismatch" and a large glucose spike, leading to "Potential Fat Storage." The figure includes avatars for a Female Scientist and Male Personal Scientist, concluding that timing is a key biological variable for food, stress, and medication response, distinguishing between what you do and when you do it.

A calorie is not just a calorie. Timing is a biological variable. 🕒

Eating the exact same meal at 8 AM vs. 8 PM produces a fundamentally different glycemic response. Stop treating your body like a static machine.

Use data to find your rhythm, not just your daily totals. 🧬

A comparative health infographic in two parts. The top half illustrates the Limitations of 'Normal' Clinical Ranges showing a general population statistical average on a bell curve, pointing out that individuals can have 'normal' results but a terrible Quality of Life. The bottom half depicts the Goal of Self-Research: 'Optimal' Personal Baseline with images of graphs on devices, a man in a crown for 'Optimized Quality of Life', and text that states Compare Individuals to Themselves, NOT the Crowd, for Actual Optimized Living and Longitudinal data is key to precision medicine. with a chart plotting personalized data over time.

Mood, pain, and fatigue aren't "soft" data—they are the ultimate endpoints.

If a biomarker improves but your lived experience doesn't, the intervention failed.

Stop optimizing for the dashboard. Start optimizing for the human.

An infographic from the SRI Self Research Institute illustrates the critical difference between "normal" clinical reference ranges and establishing an "optimal" personal baseline for health. The image is split into two comparison sections under the main title, '"Normal" Clinical Ranges are Often NOT "Optimal" for Individuals.' The left section, '"Normal" Clinical Reference Range,' shows a diverse crowd of people within a bell curve titled 'Statistical Average of Crowd.' A hand holds a lab report icon pointing to the curve with the text, 'YOUR lab results compared to GENERAL POPULATION crowd.' Further text notes, 'You can have "normal" results and feel terrible (e.g., Quality of Life).' The right section, '"Optimal" Personal Baseline,' features a detailed graph plotting multi-variable longitudinal data over time for an individual. The graph includes data points for heart rate, blood markers, and physiological deviations, alongside an optimized smiling figure with a crown, stars, and up-arrows. Text reads, 'Establish YOUR Unique Personal Baseline,' and an arrow points to the chart with the message, 'Track unique physiological deviations over time for personalized precision care.' At the bottom right, hands hold a smartphone displaying a detailed health chart. Footer text at the bottom summarizes: 'Compare Individuals to Themselves, NOT the Crowd, for Actual Optimized Living. Longitudinal data is key to precision medicine.' The SRI Self Research Institute logo is integrated at the bottom left.

"Normal" = Optimal. 📉

Clinical ranges are just population averages. You can have "normal" labs and still feel terrible.

Stop comparing yourself to the crowd. We need Personal Baselines: longitudinal data that tracks your unique deviations over time.

Self-tracking logs data. Personal science asks questions & runs experiments. 🔬

Instead of "What did my wearable say?", ask: What am I testing? What counts as evidence? Treat your life as an N-of-1 study. What experiment would you run?

What if reflective journaling had a peer-review process?
Self-research isn’t about “just writing down feelings.” It’s a structured form of inquiry: hypothesis, observation, iteration.
🧪 Journaling becomes data.
📊 Patterns become insights.
💡 Insights become change.

«Lessons in humility & simplicity for 'data science': Garmin's health status»

I blogged about how another #wearable manufacturer went down the road of leaving up data interpretation to humans instead of automating it – and how that relates to "AI" or "automated decision making"

Every person is a walking dataset.
But here’s the problem, most of that data gets lost, ignored, or locked away.

Self-research is about capturing it and turning everyday life into meaningful insights you can use to grow.

Our #personalscience wiki got a lot of LLM-generated spam posts in the past days, so it's once again time to rotate the captcha questions.

How has some fun ideas for questions "AI" struggles with? I've already added questions about the number of "R" in blueberry & strawberry 😂

Updates to the 'Personal API' In one form or another, this website has had the little widget to display some information about myself at the bottom of the page since 2018. The data is delivered through a small Django web app that regularly aggregates data from a variety of sources, picks the bits of info...

Here's some updates on the little 'Personal API' Django app I made for getting some status updates in the footer of my website.

As part of moving away from iOS, I've also replaced my Apple Watch with a Garmin device. Which means I'll have to figure out a way to get some of those data out to display it in my website footer!

Does anyone have a recommendation/existing solution for how to export small chunks of that data in […]

I keep forgetting I have a soy allergy, so if I have anything with soy sauce its goodbye to productivity and hello to brain fog, migraine, and fatigue for 4-6hrs 😩

At least i know the cause thanks to my #lifetracking & #personalscience system 😅
