This sounds extreme, but first let me ask: how many parents do you think actually keep track of their kids’ screen time? If the TV is on but one of the children wanders out of the room, does that count? What if they’re following along to a yoga video? What if the kid borrows Mom’s phone at dinner to ask Google what snails eat? Guidelines abound that encourage limiting “screen time.” Most of the research on screen time comes from studies of kids who watch TV compared to kids who don’t, as Emily Oster explains at Fivethirtyeight—and the effects typically disappear when demographic differences like income, race, and education are taken into account.
Television probably isn’t inherently bad for kids, and other tablet activities like video games shouldn’t be lumped in with TV viewing anyway. Television is passive: stuff happens, and you get to watch. ‘Screen Time’ For Kids Is Probably Fine. When I was a kid, my parents had strict television rules: no more than an hour a day, and the content must be educational.
This meant a lot of PBS. I did briefly convince my mother that the secret-agent show “MacGyver” was about science, but that boondoggle ended when she watched an episode with me. These restrictions seemed severe at the time, but my parents were just following the orders of the American Academy of Pediatrics (AAP): Children and teens should have no more than one to two hours of screen time per day, with children under 2 having no screen time at all. Those orders remain the same today. Relative to my childhood, limits on screen time have become increasingly restrictive and confusing. The iPad (and Kindle, and various other tablets) has opened up a world of “educational” screen time. If my 4-year-old is doing a workbook on the iPad, does that mean she learns less than if we used a physical workbook? Let’s consider a few examples. The amazing, surprising, Africa-driven demographic future of the Earth, in 9 charts - The Washington Post.
Traffic moves through downtown Lagos, Nigeria. (Dan Kitwood/Getty Images) The United Nations Population Division, which tracks demographic data from around the world, has dramatically revised its projections for what will happen in the next 90 years. The new statistics, based on in-depth survey data from sub-Saharan Africa, tell the story of a world poised to change drastically over the next several decades. Most rich countries will shrink and age (with a couple of important exceptions), poorer countries will expand rapidly and, maybe most significant of all, Africa will see a population explosion nearly unprecedented in human history.
If these numbers turn out to be right – they're just projections and could change significantly under unforeseen circumstances – the world of 2100 will look very different than the world of today, with implications for everyone. Here is the story of the next 90 years as predicted by UN demographic data and explained in nine charts. That's huge. 8 Horrifying Things We Do When No One's Looking. When the founders of OkCupid started one of the most popular dating sites on the Internet, they didn't intend to find out all of humanity's deep, dark secrets. All they wanted was to help people make babies. However, they accidentally ended up with a treasure trove of information about the difference between what people say (and even think) about themselves and what they actually do -- and you won't like it. By analyzing the language and behavior of OkCupid users, they've determined that you're probably a lot more racist than you think, and you can actually guess someone's race with a stunning degree of accuracy based on what they care about.

Myths about the Future that Could Ruin Your Life. @FunkyJAU Because they're both the dreams of people who believe the status of society is basically a wrong, and eventually the day is gonna come that we'll get our just desserts. For some heaven, for others Siberia or the firing squads. We're just so happy in our sinfulness/decadence, well, we don't care. On both sides it's kind of like "the world is evil, I'm right, one of these days they're gonna understand how right I was". They're both bitter fantasies against a world they feel rejects them and their values. And before you say the Marxist dreams of benefiting those people instead of tossing them in hell, I'd suggest you recall the purges.
If there were Marxist rebellions without slaughter of enemies of the people, overt or covert, I'm unaware of them. What about the covert Marxist take over of the modern media? (of course, Fox News is the exception to this!) Those aren't Marxists, those are doom peddlers. And Fox News is no exception. Education: An End to Fear - Why Students Hate Homework - Extra Credits. What are we unknowingly living in the golden age of? : AskReddit. Misguided Nostalgia for Our Paleo Pasts. By Marlene Zuk The Kobal Collection, Hammer Raquel Welch in One Million Years B.C. (1966) The first thing you have to do to study 4,000-year-old DNA is take off your clothes. I am standing with Oddný Ósk Sverrisdóttir in the airlock room next to the ancient-DNA laboratory at Uppsala University, in Sweden, preparing to see how she and her colleagues examine the bones of human beings and the animals they domesticated thousands of years ago.
These scientists are looking for signs of changes in the genes that allow us to consume dairy products past the age of weaning, when all other mammals lose the ability to digest lactose, the sugar present in milk. After that time, dairy products can cause stomach upsets. The first step is to extract the DNA from the bones.
We enter the lab, where the first thing we do is stretch another pair of gloves over the ones we just put on.
