Wearable health tech is still in its early days. These devices come with sensors that can record how many steps and how much exercise you’ve taken, how well and long you‘ve slept, stress levels, blood pressure, sun exposure, even what you’ve have eaten. Added together, all this could easily demonstrate that you’re not so sick after all.

Since some wearables are aimed at being fashionable accessories, employers might be minded to tap into the trend. So next time you’re pulling a sickie, you might need the data to back up your story.
