The human vocal tract can produce thousands of different sounds but languages use only a tiny subset of them. What happens when you try to speak a language that uses a different subset from your own?

Learn a life-saving self-rescue skill essential for all outdoors people who venture out into winter. By learning how to reduce your cold shock and get yourself out of the water with these techniques, you can save your life or help someone who has fallen through the ice to save theirs. This technique is designed for use in still water, such as a lake, and will work even if you are wearing bulky clothes. It allows you to move your body up onto ice that cannot support your standing weight, and teaches how to move over the ice until you reach ice with weight-bearing capacity.
If you are wearing skiis or snowshoes, you can first move through the cold shock portion of your self-rescue, then calmly attempt to raise your legs through applying even downward pressure with your arms on the ice shelf and arching your butt upward, followed by extending your legs out behind you. If successful, gently pull yourself forward. If this is unsuccessful, you must attempt to remove the skiis/snowshoes, or if necessary to save your life, your boots.
Cold water immersion is a potentially life-threatening situation. Do not attempt unless under professional supervision. This video was shot at the ReWild University training grounds in Wisconsin by a highly-trained wilderness instructor with rescue staff in attendance.
This is why it is important that kids experience failure and consequences for their lack of action… instead of participation trophies.
People have to learn how to apply themselves in order to be successful.

Teenagers may know full well how important final exams are – but that won’t stop some putting in minimal effort. This may be because their brains aren’t developed enough to properly assess how high the stakes are, and adapt their behaviour accordingly.
Adults are generally pretty good at being able to tell when a situation is worthy of extra time or concentration. Research has found that, when potential rewards or losses are higher, for example, adults will perform better on tasks. But this doesn’t seem to be the case for adolescents.
Catherine Insel, at Harvard University, and her team asked adolescents between the ages of 13 and 20 to play a game while lying in an fMRI brain scanner. In some rounds of the game, participants could earn 20 cents for a correct response, while an incorrect one would cost them 10 cents. But in rounds with higher stakes, correct responses were worth a dollar, and wrong answers lost the participants 50 cents.
If you live in the United States, you might have recently gotten a credit card with a microchip on it. But what does this chip do that makes it any different than the magnetic strip on the back of the card?
