In a world full of modern gadgets that is supposed to get us more productive, we have become rather more comfortable. As a consequence, we have failed to realize that this human body adds fat if it becomes too comfortable. From being active to sedentary, in spite of reduced physical activity, we certainly did not reduce or think about our daily food intake. This is where activity trackers come in, to remind you that technology is really supposed to get us more productive. The watch always reminded us to be more productive, now there are smartwatches, so we can be more productive AND healthier (smarter) at the same time.
