It's no secret, I'm a huge fan of wearables (and any gadget to be fair).  The whole concept of the Quantified Self where better insight leads to a healthier and more sustained life.

I wonder how long before the NHS or others are offering out wearables to give patients more insight into their health, activity and more and using this to improve health where appropriate.  This insight is clearly invaluable in leading to better health and wellbeing.

Acting on the insight is another thing.  As the old saying goes, you can lead a horse to water...
