Mining has been in decline since many year. The surviving companies needed to specialize in specific fields. Rare earths that are used to producing computer chips are one example. In order to keep their blue collar workers that are committing to heavy labor, they have to come up with new ideas in order to keep them healthy. A collaboration with Kentucky’s largest industry of ambulant health care services has brought up a new invention: The Smart Daylight Spender. A smart light device that calculates missing sun light hours and vitamins shortage of the workers. The light therapy helps them to recreate after long shifts as they rarely see sunlight. Happier workers with less depression symptoms have been a huge benefit since.
