> I think continued progress in the wearable sensor field...

I'm interested in people's general experience with wearable sensors - of whichever type. I wear a Fitbit (mostly for sleep tracking) but it's mostly a curiosity rather than something that offers meaningful, actionable insights.

And I'm experimenting with deliberately tracking my metrics less in other areas. As a cyclist, it's easy to get sucked into the metrics world, with easy access to HR and power, training plans, and sharing your performances online... but I found I wasn't enjoying the activity of cycling very much. A friend hypothesised that the inherent comparison and competition might be to blame, and suggested to try removing most of the data tracking; it's early days yet though.

I'd posit that avoidance of behaviours which are well-known to cause dierct harm to one's health is probably a better place to start.




I use an Apple Watch for sleep tracking and it seems to do relatively well. Whilst I haven’t found the data directly actionable, it has been useful when talking to healthcare providers in the past.
