Welcome dear guest!



About me
Thank you for visiting my website. I am Justin Timmer, Human Movement Scientist, project manager and researcher. I have this website as a hobby to understand, improve and show myself (read more about why I write). In 2013 I started with Quantified Self practices, and over the years I performed many experiments, and studies on myself using wearable devices and apps. I more and more acknowledged the importance of patterns and this made me view myself as a complex dynamical system (read more about my journey here). Below I explain the structure of the menu’s.

Complex dynamical systems
From my self-tracking activities and experiments I learned a lot about patterns, complexity and fractals, and gained a lot of knowledge about life in general. I confirmed my assumptions  through reading books/articles and watching video’s on physics, dynamics, and chaos theory. With this knowledge, I do the thing that enjoys me most; thinking about life and writing about idea’s. I use a complexity/system/fractal perspective to discover the unexplored area’s of life research. I am sharing my thoughts to inspire others, to hear criticism, and to make some of my thoughts come true. But most of all, I write about my thoughts to make my thoughts more structured, sustainable and easy to share, guiding me towards a more general theory of the mind and life. I believe this is the most beneficial reason for me to blog on my website.

Quantified Self
Every day, I track about 40 variables using apps and wearables, I have been doing this since 2013. I don’t always experiment or change behavior when I track things, nonetheless I have learned many things just by tracking my life on a daily basis. Tracking myself raised my awareness of things, confronted me with facts, showed me unexpected changes, and made me deeper investigate important things. I learned a lot about happiness (and that it is not the most important thing), about stress, my phone use, sleep, my resting heart rate, and many more life-lessons. Moreover, I experimented with many things over the past years to increase my self-understanding and to improve myself. You can find a broad range of experiments like why do i eat?, and experiment that made me twice as strong in a month without working out, or an experiment where I spend a winter in a t-shirt without feeling cold. Lastly, I wrote a few reviews on several self-tracking devices I’ve used over the past years, like the Mindwave-Mobile, the Pavlok, Muse headband, Fitbit Charge 2, Withings Blood Pressure monitor, Basis B1, and Ubiome test-kit.

I’m sure you’ll find an article you like here 🙂

Have fun reading!

    Goedemiddag Justin,

    Ik heb met belangstelling je site gelezen.
    Het is allemaal zeer herkenbaar, en ik geloof dat je gelijk hebt.
    Wanneer de mensheid vroeger net zo geleefd had als nu dan was de de mensheid allang uitgestorven.
    De mens is (wanneer ik naar mezelf kijk) geneigd de makkelijkste en comfortabelste weg te gaan. Dit heeft ook te maken met “warme gevoelens” . In een warme omgeving voelen we ons het meest prettig, wij associeren dit met liefde moederliefde, liefde naar elkaar. Ook drinken we graag een borrel vanwege het warme gevoel. We omarmen de warme gevoelens en vinden kou niet aangenaam. De mensheid is een consumptie maatschappij geworden waar de goede gevoelens nagestreefd worden.
    Jouw onderzoek is meer gericht op feiten dan dat gevoelens de boventoon voeren. Jij probeert om warme gevoelens te omzeilen door jezelf te dwingen de realiteit te ervaren als “gewoon”.

    Ik denk dat je met je onderzoek goed werk verricht.
    Alleen vind ik fruit erg lekker maar ik weet niet of dit direct met gezondheid te maken heeft, het is natuurlijk niet verkeerd maar ik zou zelf meer geneigd zijn om dingen te eten welke mensen en dieren eten die kou moeten doorstaan.

    Vergeet niet om warmte te geven aan en warmte te ontvangen van de mensen die je lief zijn.
