People don't give sleep the respect it deserves. "I'll sleep after I'm dead" is a common phrase you'll hear among workaholics. The funny part is, these people who apparently claim they "don't need" sleep or can get by with just a few hours a day are the ones who are always on edge, constantly have mood swings, can't read emotional cues, and always complain of burnout.
You know one more thing that's common among these people? They're sick. They're sick all the time! And each and every single time they'll blame it on the weather, instead of their lifestyle, food habits or work schedules. It has been proven that sleep deprivation makes you gravitate towards unhealthy foods.
