5 Things we Don't know the Facts About.

          5 Things we Don't know the Facts About.

1. Where did Dog Come From?:

 They’re some of our most constant companions, but there’s a lot we don’t know about when dogs were first domesticated, where the process happened, and what the first domesticated dogs even were
.
Studies on the subject have proven highly inconclusive, with estimates for the first domestication ranging from 9,000–34,000 years ago. Not only is that a huge gap, but it leaves a lot of unanswered questions as to how it happened. Dogs on the most distant end of that scale would have been associating with hunter-gatherer groups, while the more recent instances of domestication would have been happening when the human race had already discovered agriculture and settled into a more sedentary lifestyle.
Researchers from the University of Turku have isolated DNA from some of man’s early canine companions with some staggering implications. Some of the oldest DNA samples were taken from dogs that were living alongside humans around 33,000 years ago and were traced through to dogs that lived in Greenland about 1,000 years ago. But this particular DNA seems to be unrelated to today’s dogs, and it’s now suggested that some of the “dogs” that were domesticated for thousands of years weren’t the same as today’s dogs and were instead a sort of sister species. Ancient dogs have been found in Europe, the Middle East, and Asia, but it’s still not known if the idea of domestication spread from one area to the other or occurred independently in all areas. If it did, it’s not known who was first.

2.Is Virus A Living?: 

  For the most part, everything falls into one of two categories: It’s either alive, or it isn’t. Ever since scientists have been aware of the existence of viruses, they’ve been unable to successfully determine which of these two very distinct groups viruses belong to. Originally, viruses were thought to be alive. The scientists that discovered viruses saw them as organisms that could spread and multiply, suggesting that they were very clearly alive. By the 1930s, however, researchers from the Rockefeller University were finally able to get a look into what was going on inside a virus. Since it didn’t have any metabolic functions, they decided that it wasn’t alive.
But it’s far from clear, as further research by the same team discovered that a virus also exhibits one of the key components of life: reproduction. It not only makes more of itself but creates more proteins and internal chemical structures. Viruses have also been known to change over time, evolve, and carry on processes like repairing damage done to them. All this seems to indicate they’re alive, unless nonliving organisms are also capable of evolution, which seems like a pretty odd thing to even suggest.
Viruses are also unable to carry on these processes outside of a living host, leading some to suggest that they’re functioning on something along the lines of life borrowed from another organism—but that doesn’t make the answer any more clear.

3.Why Do We Sleep?:

   While we do know that the human body is regulated by a circadian clock that keeps humans on a sleep/wake cycle, we don’t really know why. Sleep is the time when our bodies repair tissues and perform other maintenance activities, and we spend nearly a third of our lives snoozing. Some other organisms don’t need to sleep at all, so why do we? There are a few different ideas out there, but none seem to solidly answer the question. Some theorize that animals who are able to sleep have evolved the ability to hide from predators, while others who need to remain more alert are able to rest and regenerate in other ways without fully going to sleep. While scientists don’t quite know why we do it, they are starting to learn more about why it is important, and how sleep impacts important things like brain plasticity.

4.How and Where Does Hunger  Come?:

Hunger has been a question since man had a craving for food. What makes me hungry? what is this feeling I am getting? In early years, scientists thought that hunger resulted from the stomach being empty. To prove his hypothesis one scientist even did the unthinkable and swallowed a deflated balloon. Upon reaching the stomach, he inflated the balloon. When pressure recording were taken it was shown that the stomach contracts when empty. It was found that these muscle contraction cause some food cravings and because of this scientist’s believed that this was the cause of hunger, and an empty stomach.
Further experiments were done including one where a stomach was completely removed and the results yielded that the contraction of the stomach was not the cause of hunger. After all how can a person still be hungry when there is no stomach to contract! It was found that the hypothalamus, or a section in the brain classified as the main control center, was found to be the main cause of hunger.

 As most people know, when your hungry you have an appetite.
If you have just eaten or do not crave any food this stage is called satiety because the nutrients that the body lacked has been replinished.
Lastly, anorexia is when the physiologic state of hunger is present without the desire to eat. This basically means that all though the body is asking for food, the person is ignoring its appetite basically starving themselves.
It is through these three states in which scientists are studying to figure out what makes the human body hungry.

5.Why Do We Age and At Different Rates?:

  Every day we deal with the problems of aging, ever so gradually. We’ve been doing it for as long as we’ve been a species, but we have no idea what actually causes it. We know what happens to cells as they age: Muscles lose mass, tissues become more or less rigid, connective tissues stiffen, and new cells become less and less efficient at absorbing nutrients and removing waste. We just don’t know why.
There are a couple of different theories on why cells age the way they do, including the idea that the aging process is a by-product of the body’s waste materials, or that it’s because of damage done by external factors like ultraviolet rays. It’s also been suggested that we’re simply genetically programmed to age, and how fast or how well we age has nothing to do with external factors.
Even more bizarre is the question of why we age at different rates. Looking at the methylation patterns of cells gives an indication of how old they are, and all of our cells age at different rates. Female breast tissue, for example, shows patterns and changes that indicate it’s about three years older than a person’s calendar age. At the other end of the spectrum are heart cells, which age more slowly and can actually test as being several years younger than the body as a whole. Just why the body ages as it does—and why it ages at all—is nowhere near being completely understood.

Important: Things We Don't Know it Affects The Life As a Youths/Adults/Teens.

 
Here Are The Major Thing That Affect Life
 Of The Children/Youths and Married This Days

  1. Technology's Negative effects

Neurosis 

Technology causes people to suffer from mental and emotional disturbances, such as anxiety, phobias and delusions, which are all symptoms of neurosis

. Being convinced you’re very ill after looking up strange diseases on WebMD or thinking you are famous because you have had a viral video are a couple of ways technology neurosis manifests itself.
Loss of Hearing and Eyesight
Using headphones and ear buds can cause people to lose their hearing over time. Likewise, straining your eyes looking at computer and device screens can cause people to need glasses much earlier in life.
Be more mindful of the time you spend using technology. If you have longer conversations with Siri than you do with real people, it’s probably time to put the phone down. Force yourself to have an electronic-free day or weekend. When you go on vacation, don’t take your phone or at least put it on “do not disturb”. Creating balance will help you enjoy the benefits of technology without becoming a mindless internet zombie.

  2. Drug/Alcohol Abuse

  There was a time in cinematic history where virtually every actor/actress was portrayed on screen with a cigarette in hand. Smoking, it was implied, was cool. As a result everyone was doing it, including kids. Well, as awareness to the danger of smoking increased, “cool” images of smoking disappeared. Unfortunately, the same can’t be said about drugs and alcohol. These vices are staples in everyday media. Simply, drinking and using drugs is shown as being cool.
The numbers bear the tale. 21% of high school seniors say they get high and 41% of the same group report drinking alcohol. Our kids are literally moving around in an intoxicated daze. Immature behavior is then amplified due to being under the influence. Drunk driving, poor grades and attendance, anti-social and violent behavior and the list goes on.

    3. Watching Porn/Sex Video and Images

Struthers elaborates,

1. As men fall deeper into the mental habit of fixating on [pornographic images], the exposure to them creates neural pathways. Like a path is created in the woods with each successive hiker, so do the neural paths set the course for the next time an erotic image is viewed. Over time these neural paths become wider as they are repeatedly traveled with each exposure to pornography. They become the automatic pathway through which interactions with woman are routed….They have unknowingly created a neurological circuit that imprisons their ability to see women rightly as created in God’s image (Wired For Intimacy, 85).

In a similar vein regarding porn’s effect upon the brain, Naomi Wolf writes in her article, “The Porn Myth,”

  After all, pornography works in the most basic of ways on the brain: It is Pavlovian. An orgasm is one of the biggest reinforcer imaginable. If you associate orgasm with your wife, a kiss, a scent, a body, that is what, over time, will turn you on; if you open your focus to an endless stream of ever-more-transgressive images of cybersex slaves, that is what it will take to turn you on. The ubiquity of sexual images does not free erros but dilutes it. 

4. Unemployment

The study aimed at identifying the social and psychological effects resulted from unemployment on the youth in the Jordanian community from their own perspective and their future attitudes. In addition it aimed to identify the social roles of the youth which are affected by the different problems they are exposed to because of lack of chances of work which made them anxious, depressed and fear of doing any specific work and being unable to change their life track to the best The objectives of the study were achieved through the instrument of the study which was distributed on the sample of the study. It consisted of (50) unemployed persons. The effects of the unemployment were studied in different areas represented such effects on the social life and the psychological problems of the youth, in addition to such effects on the roles of the youth in the community the findings related to the effect of the unemployment on the social problem that face the youth indicated that the delay of marriage age is the most prominent social problem. As for the psychological problems, the findings showed that the hostility feeling is the worst feeling those persons have within their community especially when comparing themselves with those who work. Finally, as for the roles of the youth, the participants showed that the unemployment causes confusion and disability of doing their own roles in the future.

   5. Violence 

   A child’s education is the foundation from which he or she will be able to go forth out into the world and build a life. Schools play a major role in this endeavor, and therefore it is reasonable to expect that these places of learning would be safe havens for the children while they are preparing for adulthood. Unfortunately, this is not always the case.

In many instances, especially in low income, urban settings, schools can be a war zone. We are not talking about minor bullying, but rather serious violence. Consider that in the last decade 284 kids were murdered due to school violence – these were shootings, stabbings, fighting and suicides. Growing up is tough enough without having to be worried about being killed while going to math class.

How to Create A Study Plan for Colleges/Universities

 

What is a study plan?

A study plan is an organized schedule that students create that outlines study times and learning goals. Just like with work or school schedules, college students should develop a study schedule where they can block off days and times in their calendar dedicated to studying. Creating a study plan not only helps you become more organized, but it also holds you accountable for your own learning outcomes. If you are an online
student, a study plan is even more important in your success in college, since you need to have self-discipline and determination to complete your studies without the constant reminders of an instructor.

Why do I need a study plan?

A study plan is an effective way to help you navigate through your college education in an organized way. Every student will develop a different study plan; there is no correct study plan for everyone. When creating your personalized study plan, you will need to do some self-evaluation of your current schedule and time management. Find days when you have fewer personal commitments when you can squeeze some study time. Remember, each student studies differently, so the amount of time you need to study will differ from the time your classmates devote to studying. Some students find that studying nightly for thirty minutes is more realistic than studying a few times a week for a longer period of time.
You’ll have to identify your learning goals for each study session in order to maximize these scheduled study times. Determine why you are studying, and develop a plan that can help you achieve those goals. Take into consideration upcoming tests, your average in certain courses, and projects that you anticipate will take more time than others.
Lastly, create a study plan that is reasonable. Although you must set aside enough time in your schedule dedicated to your studies, blocking off five hours with no break will set you up for failure. You can spend less time studying if you do it correctly. For a detailed look at how to make a personalized study plan, explore the step-by-step instructions below.

Use these four steps to create your study plan

1: Create a time chart of your current activities. Creating a time chart will allow you to see how you spend your time from day to day. For a one-week period, take notes about your daily activities. Record things like when you are at work, school, or home with family. Even note when you eat and sleep. Once you have done this for a week, look for times that you can slip in an hour of dedicated studying. This chart can be helpful for determining days and times that are consistent each week that you can devote to studying.
2: Develop a schedule – Now that you have determined available days and times for studying, make a mark in your planner or calendar. Use detailed notes to block out times on your calendar so that you are reminded every time you look at it. It is best to have a schedule written down so you don’t forget. Seeing it written down can make it seem more important, like a doctor’s appointment you cannot miss. Also, it is helpful to write down which subject you plan to study, so you can be sure devote enough time to each of your classes. For example, Mondays and Thursdays can be set aside for studying math, while Tuesdays and Fridays can be devoted to English.
3: Determine your study goals – At the beginning of each week, determine why you need to study and what you plan to accomplish in each class. Do you want to raise your average in a particular class in order to maintain a certain GPA? Are you preparing for a big exam? For example, if you are studying for an important midterm exam, alter your study plan two weeks prior to the test to incorporate review of old tests and notes in your sessions. On the other hand, when you don’t have an upcoming test, use your study time to read ahead one chapter in order to grasp the next lecture. You will need to tailor your study plan depending on your weekly goals, so be sure to analyze what you plan to get out of each study session. While it is tempting to skip your study session when there isn’t a test looming over your head, you will reduce your future test preparation time by reading ahead and preparing for lectures.
4: Stick to your schedule – A study plan works best if it is followed on a consistent basis. You should try to develop a study plan that you can follow for the length of each semester of college. Since most students enroll in different classes each semester, you will have to reevaluate your plan and fine-tune it each term. Remember, the most important thing is sticking to your plan.

Strategize for effective follow-through

One way to ensure you follow through with your plan is to schedule time for other activities. By achieving a balanced schedule, your mind will be more receptive during time devoted to studying. If you schedule several long days in a row of studying, you will get discouraged and will be tempted to give up. It is acceptable, and even recommended, that you schedule time for nonacademic activities, such as exercise, hobbies, and socializing with other students. When you are studying, remember to take breaks in order to prevent feeling overwhelmed.
Lastly, some students find it helpful to find a study partner. Studying with a classmate allows for collaboration and discussion. When creating your study plan, check with other students in your class to determine if you can coordinate study sessions. However, if you tend to socialize more than study when you are around others, stick to an independent study plan. If you do choose to study with a partner, choose someone with whom you are likely to stay on task.

Leverage tools for creating a study plan

If keeping a paper and pen schedule is not helpful to you, consider other ways for keeping your studies on track. Take advantage of study planner apps, like My Study Planner, available for smart phones and tablets, which can help you manage your study schedules. Websites like MyStudyLife.com are also helpful, allowing you to create an account to better organize your study time with to-do lists and calendars.

Tips on How to Talk to People

Hello Do you want to overcome shyness or anxiety and be confident and charismatic? Do you want to make effortless conversation with anyone, make friends and get dates easily? i think this few tips can be of help
 Scroll down to read this article.Make no mistake about it: in today’s world, knowing how to talk to people is one of the most important virtues you can possess.
If you don’t know how to talk to people it’s hard to make friends, build a social life, grab the interest of the opposite sex or get ahead in your career. But if you do, a whole lot of prospects open up in your life.

Part1: The Conversation Formula

Basically, there are 3 major components of conversation: 1) asking questions, 2) disclosing information, and 3) changing topics. Do these 3 things right, and you’ll be able to talk to people in all sorts of social settings.
Let’s take a better look at each one of these 3 components and see how you can apply them effectively in conversation.

Step 1: Asking Questions

Questions are the best conversational tool you have to get the other person to share information and engage in the conversation. Thus, you get to know them and their subjective world.
Many books and articles on making small talk will give you lists of questions to use in conversation and encourage you to memorize them. I disagree with this approach entirely.
I believe questions work best when they are genuine, when they reflect an authentic curiosity you have. If you just ask about something because you think you should, but you don’t really care about it, that will usually show.
When you’re having a chat with someone, my advice is to always think about what you honestly want to know about the other person. Then ask questions based on this.
I, for instance, am very interested in people’s careers. So I often ask people I just met “What do you do?” But if you don’t really care about this stuff, by all means, don’t ask about it. Employ your own questions.

Step 2: Sharing Information

A common mistake  that individuals who don’t comprehend how to talk to people make is they ask lots of questions to get the other person to share information, but they don’t share information themselves.
Thus, they end up bombarding their conversation partner with question after question, and the entire discussion feels more like an interrogatory.
A quality conversation combines receiving information with giving information. Even if the other person doesn’t ask you a lot of questions, don’t be afraid to disclose yourself and to share information.
For instance, if I’m on a train and the person next to me is reading a book, and I want to start a conversation with them, I might ask them “What are you reading?” After they tell me the name of the book, I might ask them “What’s it about?”
But after they answer, I usually won’t ask yet another question. Instead, I’ll make a comment apropos what they said about the book, something simple and genuine, and then I’ll tell them a bit about a book I’ve read recently and I enjoyed.
So I’ll combine asking questions with sharing information. This is what makes a conversation work.

Step 3: Changing Topics

A 5-minute conversation can be on a single topic. But long conversations typically need to go through several topics. If you want to have long conversations, which tend to build the deepest connections with people, it’s important to move it from one topic to another.
When you feel the topic you’re discussing is drying out, don’t let the conversation die. Move it to another topic.
My rule of thumb is to try and keep the topics related. For example, after I talked with a person about books for a few minutes, it makes sense to move the conversation to movies, because it’s a related topic. And from one connect topic to another, I can take the conversation anywhere.
However, it is absolutely fine if you sometimes make big shifts in the conversation subject. For example, you move from books to “So, what do you do for a living?” That’s also a normal part of conversation. Just don’t do it every 30 seconds.
By asking questions, sharing information and changing topics, you effectively make a conversation happen. You get to know the other person, they get to know you, you cover a range of topics, and you connect with each other.
The truth is basic conversation isn’t exactly rocket science.
However, I can tell you there are plenty of people who, even after they understand these principles thoroughly, still have a hard time talking to others. Add it’s not a problem related to lack of knowledge, it’s a problem related to conversation confidence.

Part 2: Building Conversation Confidence

You can have questions to ask, yet not ask them because you fret you’ll come across as rude or impertinent. You can have things to say but not say them because you fear they’re not interesting. And you can have topics you want to talk about but not do so because you worry you’ll make a fool of yourself somehow.
You see, knowing how to talk to people and being able to talk to people are two very different things.
You can understand the rules and principles, but if you have fears like the ones I mentioned (which are usually unfounded), you’ll hesitate, you won’t say very much, you’ll stumble over your words when you do, and your conversations will still be sloppy.
The only solution to this problem is to overcome your limiting beliefs and build conversation confidence. This transformation is what you should focus on above all.
 
When you have positive beliefs about yourself and you’re confident, you don’t second-guess yourself, you instinctively know what to say, you are natural and you are willing to take risks in social interactions.
At the end of the day, this is what gives you the ability to talk to people effortlessly and build the relationships you want with others, if this really help, share and comment below.
