Selective mutism is more common than autism.




Studies in California and Israel have shown that seven out of every 1000 children has selective mutism. Selective mutism (SM) is a condition in which children are unable to speak in certain situations (like school), even though they know how to speak. It’s commonly associated with anxiety, and is often misdiagnosed as autism, mental retardation, or oppositional-defiant disorder. SM has a prevalence rate of 7.1 per 1000, making it more common than autism (0.5 per 1000), major depressive disorder (0.4-3.0 per 1000), Tourette’s (0.5 per 1000), and obsessive-compulsive disorder (0.5-1.0 per 1000).

Is it true that one quarter of the area of Los Angeles is covered in cars?




Nope. This myth is fairly widespread on the internet, but it’s not accurate. As of 2007, there were 5,484,606 registered automobiles in the city of Los Angeles. Meanwhile, the city itself spans an area of 502.693 square miles. To cover one quarter of the city, the city’s five and a half million cars would need to take up an area of 125.67325 square miles or 3.5 BILLION square feet. That’s not even close to being true.

To be generous, let’s assume that the 5,484,606 automobiles registered in Los Angeles are all above average in size. For the sake of argument, let’s assume that everyone in LA drives a Hummer H1. The Hummer H1 has a width of 86.5 inches and a length of 184.5 inches. That’s a grand total of 15,959.25 square inches (about 110.8 square feet) of area covered by each automobile. That would mean that the total area covered by LA’s cars would be 607,694,345 square feet (about 22 square miles). That’s a far cry from the 3.5 BILLION square feet required to cover 25% of Los Angeles. It’s actually less than 5%. It’s probably smaller still, since most cars take up less area than the Hummer H1.

Still, LA does have a lot of cars. There are 3,792,621 people in the city, which means that there are almost twice as many cars as there are people.

Escaping from a pair of zip tie handcuffs is easier than you might think.




As demonstrated in this video, you don't have to be Harry Houdini to pull off this stunt, all you have to do is break the bindings against your back!

Your eye muscles move 100,000 times every day.




If your legs moved that much, you’d end up traveling 50 miles. The eye muscles have a special protein that keeps them from experiencing fatigue from moving so quickly. If you looked at someone’s eyes, you’ll notice that they never really stay still. Eyes are always moving.

If you fall asleep within 5 minutes of lying down, you are likely to be suffering from severe sleep deprivation.




This is also true if you feel drowsy throughout the day. Even if whatever you are doing is boring, it should not cause to you become tired. Oftentimes, sleep-deprived individuals experience brief episodes of sleep throughout the day called ‘microsleeps’ - frequently they are not even aware these episodes are occurring! We in the modern Western world are not typically very knowledgeable on this subject because severe sleep deprivation has become such a normal part of our everyday lives!
