i was reading some quantified self sceptics last night, prompted by this thread
sounds like a rabbit hole for obsessives
people who have come out the other side - after they got so deeply into measuring their activities it became an oppressive time-consuming daily chore, often for many years, say that it's like kicking an addiction, backsliding into mentally counting distances, keeping notes on moods when all they want after years of quantification is to reconnect with "intuition"
& they say it's not good for working out as you just damage yrself hitting numbers
but i think it was a learning process for them, these forlorn bloggers who publicly failed to achieve their stated aims, just that the learning doesnt come from the numbers. it comes from realisation that the body is not a machine, cause and effect in humans is impossible to measure in numbers and that any insights are illusory, triggered by false pattern recognition
of course i was looking for sceptics, so my own confirmation bias is evident there, i am consciously unquantified wherever possible, i think mainly as a way to avoid engagement with health-and-fitness-think, and/or any scrutiny of my life choices
