Are you fan of the idea of a 3-day work week? Then you and the second richest man on the planet have something in common!

Mexican telecommunications tycoon Carlos Slim wants to revolutionize the way we work by shortening our work week to just 3 days a week and lengthening the span of our career until we're in our 70s.

According to Slim, "With three work days a week, we would have more time to relax; for quality of life. Having four days [off] would be very important to generate new entertainment activities and other ways of being occupied." 

He also believes our current retirement ages date back to when people didn't live as long, and should be raised to 70 or 75. (Newser)
