"The research, published on Thursday (Sept. 27) in the academic journal Lancet Child & Adolescent Health (paywall), used data from the Adolescent Brain Cognitive Development (ABCD) study, a 10-year, longitudinal, observational study of over 4,500 children between eight and 11 years old, from 21 study sites across the US, and compared their daily exercise, technology, and sleep habits to the guidelines. The researchers then assessed the participants’ “global cognition” with standards developed by the National Institute of Health.
They found that only 5% of children met all three recommendations. Sixty-three percent of children spent more than two hours a day staring at screens, going over the screen-time limit; 82% of children failed to meet the guidelines for daily physical activity; and 49% did not get the recommended hours of sleep. Twenty-nine percent met none of the recommended standards." Quartz

I worked for a number of people who took great pride in how little they slept. 2 hours, 3 hours, etc. They all were somewhat impaired in my opinion, but they took great in boasting of this to other Type A idiots. pl
