"Quantified self" refers to self tracking and coming up with metrics in order to gain more insight and potentially improve various aspects of your life such as health (physical or mental) or performance.
I personally haven't managed to gain any significant insights from the data I've collected so far. I don't really regret it though.
Body maintenance like sleep, diet or exercise are hard for most people and also boring for many, myself included. It sucks and given the opportunity, I'd get myself independent of physical shell in a blink. However, while I'm in it:
I find that process of quantifying is fun, and even motivating for the routine!
E.g. I can't imagine going on a run without my HR monitor, because whatever the benefit exercise has and however exhausting run would be, at least I'll have a data point.
learning about routine and trying to optimize routine is also way more fun than doing the actual routine
Human body is fragile and needs constant care, but it's still a fascinating mechanism.
immunity to broscience and cargo cult
After trying to find interesting correlations in my data and failing, I've started taking most of anecdotal advice from the internet about dieting/exercise and sleep with a pile of salt and mostly ignoring it.
If I can't feel changes subjectively and I can't find them using linear regression, then surely it just doesn't matter to my body.
I want to empathize though that it's specific to my body. I'm lucky to be healthy enough so I don't have anything obvious to 'fix'. I do know people who claim minor things changed the way they e.g. sleep, so I don't want to devalue others' experiences.
But if you do stress over so many (often contradictory) advises like I used to, I'd recommend trying to set up proper experiments and measure. Numbers don't lie, or at least harder to trick.
- collecting data is valuable for #lifelogging
- finding my baseline while I'm healthy for potential future health issues

Lifelogging is not a new concept as people have kept diaries for centuries. However these days it's particularly easy to do because lots of it can be automated and collected passively from your digital trace.
Personally I do it because I find it fun, having access to your activities from the past is very satisfying and compensates for decaying memory and it fits well along the #quantified-self lines.
Extended mind is the idea that your mind isn't limited by your physical body, but augmented by external means.
¶I like that analogy particularly: The Extended Mind – 1000-Word Philosophy: An Introductory Anthology, in 'Inga and Otto' section
Perhaps because it resonates with me most and was the main reason I started my quest for better personal information management.
PKM stands for Personal Knowledge Management (I agree it's a somewhat clumsy acronym). It refers to strategies and tools for efficient information management, which is particularly important these days in abundance of information around us.
Specifically, when I talk about it I mostly refer to digital knowledge management and ways of seamless integration with our meaty brains. I write more about it here.
Human brains seem to be best for generating new ideas. I want to learn more, think faster, distract less, interact and visualize, effortlessly remember everything; not memorize and do routine information processing, which computers seem better at.
I haven't thought much of a specific roadmap, but my vision is:
- ultimate goal is of course merging with the machine/cloud/God, or whatever else you wish for yourself when the Singularity happens
- medium term thing might be some sort of neuroimplant/brain-computer interface, but sadly technology doesn't seem to be there (apart from experimental devices that help people with dementia or other serious brain conditions)
- what we realistically can and capable of doing now is developing tools to make the knowledge accessible on your fingertips with existing technology as computers and smartphones
The latter bit is what I'm trying to do and developing simple but working tools (rather than sketching prototypes that look beautiful but never make it). Even though stuff we have at disposal at the moment (often lousy internet connection, OCR, basic speech and pattern recognition, text search, 2D screens, touchscreens and basic VR/AR) is not so exciting and somewhat restricted, I feel we're not fully utilizing it anyway yet.

Annotation is the process of adding a layer of personal (with a potential for sharing) metadata on top of existing content such as highlights, notes, anchors etc.
- I'm writing more about it here.
For most of modern web services, data is too centralized and only accessible from the services cloud, which makes applications unusable if you lost Internet connection.
What is more, imagine if something horrible happens say to Gmail servers and the emails are completely wiped from them. Geeks like me and you might do occasional backups, but most people will lose their personal data forever. E.g. it's somewhat scary how many people rely on Google Photos only to store their memories.
Some of IT giants are already too big to fail and when they have brief periods of downtime, they take a good chunk of internet with them. Governments are blocking access because they control ISPs at the moment. All this is just dangerous (it literally feels dangerous if you consider your digital trace as your essential part).
We need to make it easier for normal users to own (at least as in 'own a copy') of their data. We need to find ways of bringing better network resilience and ideally fully offline mode or easier ways of selfhosting/setting up personal clouds.
This is also good for privacy and security, because potentially you can have software that doesn't even have permissions to access the internet as long as you are using your own means of synchronizing data.
Some related links:
I write lots of various scripts and tools to simplify my life and experiment. Most of them I open source.
My alternative self (not necessarily in the sense of many worlds interpretation) is doing some cool physics research.
I took a different path, so for the past few years in my spare time I'm slowly picking up modern physics, at the moment: quantum field theory and general relativity. In the process, however, I've massively distracted on this blog, and various tools that would help me utilize my knowledge better :)
Even if I never achieve anything new, that's still worth it. Through learning physics I can:
- appreciate nature
understand contemporary philosophy (in particular, philosophy of mind)
I'm also glad to have studied computer science, it's a massive boost.
not have existential fear
- learn lots of otherwise useful math
There are some potential short term benefits:
makes you more resilient
Something along the lines of #prepping. Realistically though, in modern world, it's nice to be able to run after a bus or up the stairs, but it's quite questionable if running, say, even 5K is useful.
makes you appear better physically
Nice bonus, but I don't find it as a good value for time spent.
feeling better immediately after exercise
I used to get that, but it seems that the body adapted and I can't feel endorphine kick anymore. There is some good feeling about yourself having willpower to stick to routine, but I'd rather not have the routine in the first place.
feeling better generally (less stressed, better sleep etc)
I suppose I'm lucky to feel good anyway, so I don't feel subjective impact of exercise on my well being. Objectively, I tried to find correlations between amount of exercise and sleep, and failed to find any. (I'll write about it in more details later)
I absolutely hate it. It's a massive drain of time and willpower. In addition, it comes with all sorts of logistical difficulties: gym outfit, shower, backpack, eating, weather.
That said, I'm doing it regularly and it's part of my routine. What made me really serious about it is the quote here:
Even ignoring quality of life you are looking at a 3-7 fold return on every minute you spend exercising in extended life, perhaps even exceeding that if you are making optimal use of your time.
Something just clicked and I was consistent since reading this. Even 1-fold return would worth it: basically you gain free consciousness (quality of thinking is shit when I exercise, but it's better than nothing). This estimate should be used carefully though, returns are, of course, not linear, otherwise power athletes would have much longer lifespans.
So, yes, long term benefits. It seems that pretty much all studies find correlation between activity level and longevity. Sadly, the recommendations vary wildly and are extremely vague, e.g. from NHS website:
do at least 150 minutes of moderate intensity activity a week or 75 minutes of vigorous intensity activity a week
Examples of moderate intensity activities: brisk walking, water aerobics, riding a bike
Examples of vigorous activities: jogging or running, riding a bike fast or on hills, skipping rope
I have no idea what is that supposed to mean: 8 km/h running and 15 km/h are all running, but everyone would agree that it's quite different! How fast is riding bike 'fast'?
You can also achieve your weekly activity target with: several short sessions of very vigorous intensity activity a mix of moderate, vigorous and very vigorous intensity activity
Duh! I understand that NHS cares about averages (as it should!) and most people don't give a shit about details and just want some simple instructions. Also recommendations will probably vary depending on people's genetics anyway.
That's one of my primary motivations behind #quantified-self: I want to understand how exercise impacts my body. For now I'm mainly just collecting data and doing various plots/analyses.
No amount of exercise is going to prevent your body from failing you. If I knew for sure that, say, in 20 years, there would be some sort of technology that can compensate for not doing regular exercise, I'd stop it in a blink. Since I don't have this certainty, I hope that by sticking to routine I can buy some time till the #singularity happens.
