Who would not love to see people smile. Her face always looks fresh and cheerful. Smiles was able to extend life up to seven years.

A study found that with a big smile creases around the eyes which can prolong life more deeply. This study adds evidence that pleasure and happiness can have a strong impact on the health and life expectancy.

Researchers believe that a wide grin and the creases around the eyes reflecting the underlying positive outlook on life that translates into long-term health is better.

This conclusion emerged from the study of old photographs. The experts at Wayne State University, Michigan, studied 230 major league baseball player photos printed in the 1952 Baseball Register.

Each registered player statistics, such as date of birth, weight, marital status and employment details.

As quoted from Dailymail, researchers rank each player based on whether they did not smile at all and smile in part, where only the muscles around the mouth are involved, or a big smile by lifting the cheeks and folds around the eyes.

The researchers then compared the images with the lifetime of every player. The results showed that out of 184 players who now are dead, they are in the category of ‘no smile’, and has an average life of 72.9 years.

They are smiling in part, have an average age of more than 75 years. But those who smiled broadly have an average life of up to 79.9 years.

The study, published in the journal Psychological Science confirms fake smile can not provide the same benefits, because of extra life expectancy is only visible to players who actually smiling, which is known as the Duchenne smile.

Duchenne smile is a smile that involves the muscles around the mouth and eyes. While a smile ‘non Duchenne’ only influence the shape of the mouth. Duchenne taken from the name of a neurologist on the 19th century which defines in detail smile.

Other findings that support also showed that the happiness and smiles can reduce the risk of heart disease.

Scientists who examined more than 1,700 people over the past ten years found that people with anxiety and depression are more likely to suffer from clogged arteries and high blood pressure.

When you want a long life, begin to improve the quality of sleep. A study proved that most people who reach the age of 100 years have a good sleep quality.

“The age and health condition are two things that are most influenced by the duration and quality of sleep,” said Danan Gu, Ph.D. from Portland State University who led the study, quoted from ScienceDaily.

Since 2005, Gu and his colleagues made observations of China’s 15 638 residents aged 65 years and over, in all 22 provinces. A total of 2794 in antarnya aged 100 years or more, while those aged 90-97 years as many as 3927 people.

Sleep quality in 65 percent of participants were categorized as good and very good, with an average duration of 7.5 hours a day including naps. Surprisingly, participants with the age of 100 years and over have the sleep quality better than 70 percent of 65-79 year-old.

Health issues are also closely related to the quality of sleep. Experience deep sleep on the participants who have health problems observed 46 percent lower. This happened to participants who are experiencing anxiety, chronic illness, and routine life unpleasant.

Another fact which is revealed, the relationship between the sexes with sleep quality. Experience deep sleep on male participants 23 percent more than in female participants.

This survey was not designed to actually see the cause-effect relationships. However, from existing data, the authors believe there is strong correlation between quality of sleep to health and longevity.

China deliberately chosen as the location of the study, because the elderly population in the region recorded the highest in the world. Based on World Bank data (World Bank), nearly 40.5 million of the total 1.3 billion population of China has the age of 75 years and over.

Observations since 2005 have been published in the journal Sleep. At the end of this year, the same team will also publish the years 2008-2009 as the comparison data.

The cause of abdominal sounds

The human stomach sometimes prefer certain sounds. Of course this could create embarrassment if the owner’s stomach was in a quiet room. What causes the stomach to make a sound?

Belly rings can be a reminder, but the voice is sometimes hard stomach or slowly can also no reason at all.

This growling sound coming from the stomach and small intestine and may relate to the functions of the digestive tract. Digestive system is basically a long tube that starts from the mouth and ends at the anus. These tubes connect the various organs and other parts associated with the digestive system.

How to encourage the food in the human digestive system is the wave of muscle contractions that move continuously to push it down with a movement called peristalsis. In addition to encouraging food, these contractions also help stir the food and digestive juices that are different so that the sticky mixture called chyme.

As quoted from HowStuffWorks, belly rings are the result of this process encourages the movement of food between solids, liquids chyme and the existence of gas and air. Stomach that reads this can happen at any time not only to the extent when a person feels hungry. But if there is food in the stomach or small intestine, hence the sound produced is a little more calmly and slowly.

Why muscle contraction has occurred even though the stomach is still empty?

The reason is related to the sense of hunger and appetite. After two hours on an empty stomach, the stomach begins to produce more hormones that can stimulate local nerves to send messages to the brain. Furthermore, the brain will respond by giving the signals on the digestive muscles to restart the peristaltic movement.

This is the first peristaltic movement to clean up food scraps which are not digested, then this movement will make a person feel hungry again. This muscle contraction will occur every hour and lasted 10-20 minutes, until the stomach fills with food.

But if the sound produced by the stomach is too excessive, it may be that is one sign that something was wrong in the stomach such as irritable bowel syndrome. In this case the complaint is usually followed by another in the gastrointestinal area.

So a way to control the sound of the stomach is to eat small meals and avoid eating a heavy direct and less foods containing gas so that the sound is not getting bigger.
