happiness meaning research

  • One can find meaning in life and be unhappy at the same time. Aaker points out that this type of life has received less attention in the media, which has recently focused on how to cultivate the happy life.  Examples of highly meaningful, but not necessarily happy, lives may include nursing, social work or even activism. The unhappy but meaningful life involves difficult undertakings and can be characterized by stress, struggle and challenges. However, while sometimes unhappy in the moment, these people – connected to a larger sense of purpose and value – make positive contributions to society. Happiness without meaning is characterized by a relatively shallow and often self-oriented life, in which things go well, needs and desires are easily satisfied, and difficult or taxing entanglements are avoided, the report noted. And so, the meaningful life guides actions from the past through the present to the future, giving one a sense of direction. It offers ways to value good and bad alike, and gives us justifications for our aspirations. From achieving our goals to regarding ourselves in a positive light, a life of meaningfulness is considerably different than mere happiness. "People have strong inner desires that shape their lives with purpose and focus – qualities that ultimately make for a uniquely human experience," said Aaker.

      Happiness comes from having stuff only if you think about happiness like that. Happiness actually comes from not being stressed and trying to be with your family.

      People think that happiness comes from having phones,toys,etc.but thats the problem,Thanks to other peoples blogs and myths people think that the only way to be happy is from having stuff,and from having the "Happiness stuff" comes being "Buried alive".

      Being happy is not about having stuff,its about being with your family,Happiness is the best thing that can happen to anybody.Happiness is kind of the meaning of life,it gives us a meaning of what to do and when to do it.Happiness gives us a path to life,happiness is when you are with your family,happiness helps us understand that we can do better than what we already do.Happiness as you know doesn't come from having stuff,

      Happiness is also known as a goal of life.It represents us as who we are. Happiness shows on our face.It makes other people see our pride sometimes other people feel our pride so much that they show their pride,and the happiness influence goes and goes until at some point it stops.nI clearly think that if it wasn't for happiness,pride and making our goals (Not soccer goals) we would still be cavemen and cavewomen because without them we would be terrible we would feel stupid we would feel so dum that not even Benjamin Franklin would've created the light because he probably would've felt stupid. So thats why being happy is important because without happiness we wouldn't have accomplished anything.And look at us now we already went to the moon we made a tv we made a telephone and now we have iphones.it all happened thanks to our 1 and greatest feeling:Happiness.

      Sometimes people feel sad and depressed so they go to the mall and go buy clothes and other items,then they claim to be relaxed and happy but Jennifer Aaker proved that its not true.In fact she proved that there are lots of ways to be happy but only 1 way is the most true hearted : Social work and also being with your family.But you cant be happy by just standing besides your family,you would have to be social with them.
  • A Stanford research project explored the key differences between lives of happiness and meaningfulness. While the two are similar, dramatic differences exist – and one should not underestimate the power of meaningfulness. "The quest for meaning is a key part of what makes us human," the researchers concluded.

"The quest for meaning is a key part of what makes us human," the researchers concluded. BY CLIFTON B. PARKER Social psychologist Jennifer Aaker studies happiness and meaningfulness in life. While lives of meaningfulness and happiness overlap, they are distinctly different, according to Stanford research. But not everybody understands that happiness comes from within not from having or buying stuff. 50% of the world population (Not counting the babies) thinks that the more stuff they got or get the happier they'll be!But of course that we the "smart" population think otherwise. Social psychologist Jennifer Aaker has studied her whole life everything about happiness and she taught us that happiness comes from within happiness comes from smiling everyday from being social with friends or family.Happiness doesn't come from having stuff not at all!! Happiness is the greatest gift of all,happiness isnt just a feeling,happiness is a friendly shadow that follows you everywhere only if you let it.

      The Stanford research project of Jennifer Aaker explains how to get happiness and why it is important.But now I realize that not everybody understands that happiness comes from within not from having or buying stuff. 50% of the world population (Not counting the babies) thinks that the more stuff they got or get the happier they'll be!But of course that we the "smart" population think otherwise. Social psychologist Jennifer Aaker has studied her whole life everything about happiness and she taught us that happiness comes from within happiness comes from smiling everyday from being social with friends or family.Happiness doesn't come from having stuff not at all!! Happiness is the greatest gift of all,happiness isn't just a feeling,happiness is a friendly shadow that follows you everywhere only if you let it.When I say that happiness is a shadow following you only if you let it its because this days happiness is a complete shadow.Not everybody is happy and someday we might never feel happiness ever again,But while I get off topic you should think : "Wow,I should listen to her.I should be grateful for what I already have, instead of getting more stuff." Because the more you think about it the more you understand that happiness is our path to life.that happiness is our friend happiness is our heart that keeps us alive.Thats why we smile thats why we cry thats why we love laugh and live. Without happiness we would be grumpier than the grumpiest cat.We should think more about being grateful than thinking of what to buy to be happy.

      Dinosaurs were getting smaller they developed traits to survive. 
  • The researchers believe that miniaturisation and the development of bird-like traits had a joint influence on the evolution of the dinosaurs into today's birds. Professor Michael Benton, from the University of Bristol's school of earth sciences, said: "This study means we can't see the origin of birds as a sudden or dramatic event, with a dinosaur becoming a powered flyer overnight. "The functions of each special feature of birds changed over time - feathers first for insulation, and later co-opted for flight; early reductions in body size perhaps for other reasons, and later they were small enough for powered flight; improvements in sense of sight and enlargement of brain - even a small improvement in these is advantageous. "So perhaps it's a long-term trend associated with deputation to a new set of habitats, in the trees, to avoid predation, and to exploit new food resources."

Why We're So Materialistic, Even Though It Doesn't Make Us Happy - 0 views

  • We tend to equate buying things with positive emotions. Subsequently, we think that purchasing new stuff makes us happy. It's a pretty clear correlation. In a study published in Neuron, researchers looked at what's going on in the brain when we think about buying stuff. When a product image flashed before people's eyes, an area of the brain called the nucleus accumbens lit up when a subject liked what they saw. Essentially, the brain's pleasure center kicks into gear and floods the brain with dopamine at the very thought of getting something we want. The weirdest thing about this is that just thinking about buying something is pretty much the same as actually buying it.

      We want to buy things,we make our brain think : "the more I buy things the happier I will be,LETS BUY MORE STUFF!"
  • "Thinking about acquisition provides momentary happiness boosts to materialistic people, and because they tend to think about acquisition a lot, such thoughts have the potential to provide frequent mood boosts," Richins wrote, "but the positive emotions associated with acquisition are short-lived. Although materialists still experience positive emotions after making a purchase, these emotions are less intense than before they actually acquire a product."
  • It's probably no surprise to most of us, but study after study shows that buying stuff doesn't make us happy. More importantly, we're actually unhappy when we put too much value on material objects.The big problem here isn't just that we're a little bummed out when someone else has more stuff than we do. It's that when we put a lot of emphasis on materialistic value, we're prone to depression, personality disorders, and more. One study from

  • “Crying is a natural emotional response to certain feelings, usually sadness and hurt. But then people [also] cry under other circumstances and occasions," says Stephen Sideroff, PhD, a staff psychologist at Santa Monica--University of California Los Angeles & Orthopaedic Hospital."People cry in response to something of beauty. There, I use the word 'melting.' They are letting go of their guard, their defenses, tapping into a place deep inside themselves."

      Crying is something created by emotions and feelings such as sadness and pain. But people also cry because they want. People cry because you reach the highest limit of your eyes like when you hit it hurt so much and the hurt goes to all of your body so you destroy your defense/guard and  let the tears pass your eye from deep inside you.
  • Crying may also have a biochemical purpose. It's believed to release stress hormones or toxins from the body, says Lauren Bylsma, a PhD student at the University of South Florida in Tampa, whose research has focused on crying.

Five Stages Of Sleep ... Sleep Cycles Explained - 2 views

stages sleep

shared by lobo5879 on 03 Nov 14 - No Cached
  • Stage 1This is the lightest stage of sleep, the transition phase, where you feel yourself drifting off. If you were to forget about the alarm clock and allow yourself to wake up naturally, Stage 1 sleep would be the last stage before you fully wake up. You don't spend too much time in Stage 1 sleep, typically five to 10 minutes, just enough to allow your body to slow down and your muscles to relax.
    • lobo5879
      lobo5879 on 04 Nov 14
       
      The stage 1 of sleep is when you are starting to relax your muscles and start to sleep. This stages is not very long it is about 5 to ten minutes. This stage is when you wake up more quickly for example if someone touches you you will easily wake up.
  • Stage 2The second stage of sleep is still considered light sleep. Your brain activity starts to slow down, as well as your heart rate and breathing. Your body temperature falls a little and you're beginning to reach a state of total relaxation in preparation for the deeper sleep to come.
  • Stage 3Stage 3 sleep is the start of deep sleep, also known as slow wave sleep. During stage 3, your brain waves are slow "delta waves," although there may still be short bursts of faster of brain activity (also known as beta-waves). If you were to get awakened suddenly during this stage, you would be groggy and confused, and find it difficult to focus at first.
    • lobo5879
      lobo5879 on 04 Nov 14
       
      this stage is when your body is finishing to relax and example is: if someone trys to wake you up you would be confused and do not know what is happening because you were already finishing to completely relax
  • ...3 more annotations...
  • Stage 4Of the five stages of sleep, this is the one when you experience your deepest sleep of the night. Your brain only shows delta-wave (slow wave) activity, and it's difficult to wake someone up when they're in Stage 4 of sleep.

      lobo5879 on 04 Nov 14
       
      this stage i when you are more hardly to be awaken. In this stage is when you start to dream and this stage is when the kids start having nightmares
  • It's during Stage 4 sleep that children are most likely to suffer from bedwetting or sleep terrors. Stages 3 and 4 can last anywhere from 5 - 15 minutes each, but the first deep sleep of the night is more likely to be an hour or so. This is the time when the body does most of it's repair work and regeneration.
  • Stage 5 This is the stage of sleep when you dream. It is also referred to as "active sleep" or REM sleep, which stands for the rapid eye movements that characterize Stage 5. During REM sleep, your blood flow, breathing, and brain activity increases. An EEG would show that your brain is about as active as it is when you're awake.Another aspect of Stage 5 sleep is that the muscles in your arms and legs will go through periods of paralysis. Scientists speculate that this may be nature's way of protecting us from acting out our dreams.The first period of REM sleep of the night usually begins about 90 minutes after you start drifting off, and lasts for about 10 minutes. As the night passes, the periods of REM sleep become longer, with the final episode lasting an hour or so.Babies may spend as much as half of the time they're asleep in the REM phase. For a healthy adult, Stage 5 occurs for about 20 to 25% of the time you are sleeping, and decreases with age.Scientists and researchers are continually learning more about the mechanics and physiological effects of sleep, and what happens during the five stages of sleep.

The four Galileans are all over 3,100 kilometres (1,900 mi) in diameter; the largest Galilean, Ganymede, is the ninth largest object in the Solar System, after the Sun and seven of the planets (Ganymede being larger than Mercury). All other Jovian moons are less than 250 kilometres (160 mi) in diameter, with most barely exceeding 5 kilometres (3.1 mi). Orbital shapes range from nearly perfectly circular to highly eccentric and inclined, and many revolve in the direction opposite to Jupiter's spin (retrograde motion). Orbital periods range from seven hours (taking less time than Jupiter does to spin around its axis), to some three thousand times more (almost three Earth years).

cry eyes reasons works facts

  • 1. Tears help us see. Starting with the most basic function of tears, they enable us to see. Literally. Tears not only lubricate our eyeballs and eyelids, they also prevent dehydration of our various mucous membranes. No lubrication, no eyesight. Writes Bergman: “Without tears, life would be drastically different for humans–in the short run enormously uncomfortable, and in the long run eyesight would be blocked out altogether.”
  • 2. Tears kill bacteria. No need for Clorox wipes. We’ve got tears! Our own antibacterial and antiviral agent working for us, fighting off all the germs we pick up on community computers, shopping carts, public sinks, and all those places the nasty little guys make their homes and procreate. Tears contain lysozyme, a fluid that the germ-a-phobic dreams about in her sleep, because it can kill 90 to 95 percent of all bacteria in just five to 10 minutes! Which translates, I’m guessing, to three months’ worth of colds and stomach viruses.
  • 3. Tears remove toxins. Biochemist William Frey, who has been researching tears for as long as I’ve been searching for sanity, found in one
  • ...5 more annotations...
  • study that emotional tears–those formed in distress or grief–contained more toxic byproducts than tears of irritation (think onion peeling). Are tears toxic then? No! They actually remove toxins from our body that build up courtesy of stress. They are like a natural therapy or massage session, but they cost a lot less!
  • 4. Crying can elevate mood. Do you know what your manganese level is? No, neither do I. But chances are that you will feel better if it’s lower because overexposure to manganese can cause bad stuff: anxiety, nervousness, irritability, fatigue, aggression, emotional disturbance and the rest of the feelings that live inside my happy head rent-free. The act of crying can lower a person’s manganese level. And just like with the toxins I mentioned in my last point, emotional tears contain 24 percent higher albumin protein concentration–responsible for transporting many small molecules (which has to be a good thing, right?)–than irritation tears.
  • 5. Crying lowers stress. Tears really are like perspiration in that exercising and crying both relieve stress. For real. In his article, Bergman explains that tears remove some of the chemicals built up in the body from stress, like the endorphin leucine-enkaphalin and prolactin, the hormone I overproduce because of my pituitary tumor that affects my mood and stress tolerance. The opposite is true too. Bergman writes, “Suppressing tears increases stress levels, and contributes to diseases aggravated by stress, such as high blood pressure, heart problems, and peptic ulcers.
  • 6. Tears build community. In her “Science Digest” article, writer Ashley Montagu argued that crying not only contributes to good health, but it also builds community. I know what you’re thinking: “Well, yeah, but not the right kind of community. I mean, I might ask the woman bawling her eyes out behind me in church what’s wrong or if I can help her, but I’m certainly not going to invite her to dinner.” I beg to differ. As a prolific crier, especially on video, I always come away astounded by the comments … the resounding support of people I know all that well, and the level of intimacy exchanged among them. Read for yourselves some of the comments on both my self-esteem video and my recent death and dying video and you’ll appreciate my point. Tears help communication and foster community.
  • 7. Tears release feelings. Even if you haven’t just been through something traumatic or are severely depressed, the average Jo goes through his day accumulating conflicts and resentments. Sometimes they gather inside the limbic system of the brain and in certain corners of the heart. Crying is cathartic. It lets the devils out. Before they wreak all kind of havoc with the nervous and cardiovascular systems. Writes John Bradshaw in his bestseller “Home Coming”: “All these feelings need to be felt. We need to stomp and storm; to sob and cry; to perspire and tremble.” Amen, Brother Bradford!

  • "Dinosaurs became ever more 'birdy' over time," Brusatte said, but there was no single missing link, he added. Birds and dinosaurs are like two colors in a rainbow, he said — you can recognize each, but they bleed into each other at their borders.

      Scientists think that dinosaurs and birds were connected, not only because they look alike, but because their blood is identical... 
  • The new pedigree of carnivorous dinosaur evolution is the most comprehensive one ever assembled, the researchers say. The findings show that birdlike features such as wings and feathers developed slowly over tens of millions of years.

      Dinosaurs evolved to birds, and it happened slowly, it took millions of years for dinosaurs to evolve into birds... Even though they were always changing, they grew feathers, then developed flying skills!
  • The label of "bird" is somewhat arbitrary, but scientists consider the feathered fossil Archaeopteryx to be the first of the group, Brusatte said. "What probably distinguishes birds is the ability to have powered flight," he said, though it's possible that other dinosaurs could fly too.

      We predict that  Archaeopteryx a very early bird, that looks like a dinosaur, and lives with the dinosaurs is what made the birds of today fly!

  • the earliest birds would have been indistinguishable from their closest relatives.

      The earliest birds such as Archaeopteryx were really hard identify because they were so different compared to the birds we have today!

      Homework can be heavy work for kids.And sometimes the homework that you are assigned aren't the needs of some students.Homework not just stresses kids it also stresses family. Research shows 90% of americans who do have homework can't have practice for social abilities.For example you can't have time for friends.
