It makes our society even more results-driven and number-driven than I would like it to be.

I do understand what you are saying and I actually have much the same view, but will play devil's advocate a little more.

Perhaps this is a good thing as it puts the numbers on the surface, instead of hidden away. The numbers of our lives are there, especially digitally. The large handful of data gatherers have digital avatars created for all of us, and they use those numbers - while we don't even know they exist.

I will listen to my body and look in the mirror, and that will have to do :)

Yes, then there will be the jobs, the kids, the pressures, the whatevers that arise - and before you know it, you look in the mirror and not like what you see, lose confidence in who you are perhaps.

We are already gamified, most of just don't pay attention to the metrics that matter, even to ourselves. Regardless of whether we track them or not, they tick along, or don't.
