Is it possible to predict earthquakes? In 2009, a man in L’Aquila, Italy saw flickering lights dancing above the stone street. He immediately knew what to do and moved his family to a safer place. Only seconds later, a massive 8.3 magnitude earthquake hit the whole region. His knowledge of the strange lights saved his and his family’s lives. So what are those mysterious warnings? For centuries people interpreted the lights as something otherworldly. The scientific community didn’t take them seriously, just put them down to a false recollection, a mind trick, or pure imagination. Then came the invention of photography, and more and more evidence of the earthquake lights appeared. That physical evidence wasn't as easy to dismiss as old legends were.

We are all guilty of adding some sugar here and there to make things taste better, but what might seem like innocent pleasure can actually cause a lot of serious health issues when we put too much sugar in our body. Luckily, our system gives us crystal-clear signs when we’ve crossed that line and should stop doing that immediately to protect ourselves from health problems. Large amounts of sugar in your diet cause your cells to go through complicated biochemical processes that result in muscle aches and pains, joint stiffness and swelling. Food high in sugar won’t make you feel full because it doesn’t contain any useful nutrients, which is why you often feel hungry even if you just ate a big delicious sugary muffin like half an hour ago. When you eat sweet stuff, the pancreas releases insulin to help bring glucose to the cells, giving you a rush of energy. Once the cycle ends, though, your energy levels drop because your body wants more sugar. And this can start a never-ending cycle of overeating sugar in order to stay energized. If not brushed away properly, food debris causes the appearance of plaque on your teeth, which erodes the tooth’s hard enamel surface resulting in tiny holes. Always make sure to brush AND floss your teeth properly, use an antibacterial mouthwash, and visit your dentist regularly. Bloating is directly connected to what you eat and how your body can digest it. If sugar isn’t absorbed into the small intestine (and not all of it will if there’s too much of it), it’ll enter the large intestine where it usually acts like gas-producing bacteria.

Raising children is very difficult and no one has the right to judge someone's particular parenting style. However, some parenting mistakes are more dangerous than others and can seriously damage your child’s health. This video will help you find out what actually affects a child’s psyche and teach those who have toxic parents how they can deal with this issue. When raised by narcissistic parents, children suffer from slowed-down emotional development or none at all, will most likely suffer from depression, anxiety, or post-traumatic stress disorder when they become adults and grow up into an adult that’s either a self-saboteur or a person ready to sacrifice everything to achieve high goals. Children of toxic parents live in constant fear and apprehension. They’ll grow up into teenagers forced to listen to their parents' complaints, adjust to a "complicated situation", put themselves in their parents' shoes, and help, tolerate, and console them. Toxic parents might not see anything wrong whatsoever in telling all the relatives, neighbors, and family friends that deeply sensitive information the child was pressured into disclosing. These types of parents instill an inferiority complex in their kids since they don't wanna see their child try new things and succeed. Their narcissistic self-love generates fear at the thought of their child becoming better, smarter, and more successful than they are. These parents seem to “generously” offer something that their children don’t really need, but any refusal causes resentment. A grown kid starts thinking, "My parents probably just want some company and wanna feel needed." So they accept the help, thank the parents, and offer something in return. But there's no happy ending here because the parents will always remind their children of that "favor" they did for them. Learn more about your ad choices. Visit megaphone.fm/adchoices

Wisdom teeth come out between the ages of 12 to 25, and some doctors recommend having them removed. But is it necessary? Do we really need to get our wisdom teeth pulled? In some cases, there is absolutely no need to remove your wisdom teeth. If they don’t interfere with the normal functioning of neighboring teeth, it means that your mouth is big enough to accommodate all four of your wisdom teeth. The same is true if they’re straight and not at an angle to their neighbors, which can create hard-to-reach places for bacteria to grow. If there isn't enough space in the mouth and all adjacent teeth are already snug as it is, the erupting wisdom tooth brings the risk of damaging the nearby teeth. In this case, it’ll cause pain in your whole mouth and problems with chewing! Poor oral hygiene because of stuck food in wisdom teeth that didn’t’ fully come in can cause a large buildup of bacteria, which can lead to even more problems like oral cavity diseases. Most dentists agree that the younger you are when you have your wisdom teeth removed, the better. After you turn 25, all the bone tissues have formed completely. This means that the teeth are more difficult to remove, and the surrounding tissues heal more slowly. After you’ve had your wisdom teeth removed, the best post-op diet for you is milkshakes and ice cream. These foods are soft and cold, which is good because it soothes the pain.

Why are planes slow? Everything else is speeding up: smartphones, the Internet, the pace of life in general! So when are we going to get a superfast passenger jet that can cross continents in the time it takes to watch just one inflight movie versus several? Speed has always interested engineers and pilots. At least at first, they were pretty good at getting these metal birds to fly faster and faster. As long ago as in 1945, a German test pilot reached a speed of 610 mph. But then, something happened and speed stopped growing. Any guesses why? Learn more about your ad choices. Visit megaphone.fm/adchoices

Tantrums are very common in kids aged 1 to 4. More than half of kids let their frustration out at least once a week, or more often. Why do they do it? By the time they turn 3 or 4, kids have much better language skills than babies, of course, but their vocabulary is still not advanced enough to describe everything they feel. So what can you do to prevent your kids from going crazy now and then? Learn more about your ad choices. Visit megaphone.fm/adchoices
