Why do we have 32 teeth?

Adult humans have 32 teeth in their mouth. These teeth perform different functions. Let’s know some details about how all these teeth names, how they work in our mouth and the teeth numbers.

9 Facts About Sneezing You Didn't Know

Sneezing is an important part of our body’s defense mechanism. Through this process, the body removes an irritation from the nose, caused by intake of any foreign object through breathing. When we breathe, the foreign particles enter our nose. Sensors present inside the nose detect these foreign objects. They further signal the cilia, which are hair like paddles lining our nostrils and sinuses, to create a movement to expel the foreign bodies. The burst of air produced by sneeze clears all the nasal passageways expelling the irritants out of the nose. The nose is often underestimated in the efforts of taking care of our body’s health. The common irritants causing the sneeze include dust, cold air or pepper. People allergic to some other objects might also trigger sneezing. Whenever any of these objects tries to attack the system while entering through the nostrils, the sneeze system comes into play and saves us from many germs and bacteria who could have made a permanent home in the moist area inside our nostrils. The system really helps keep the body healthy. Here are some of the strange facts about sneezing that you might not have known before.

7 Benefits of Body Hair That You Didn't Know

Thing are not as useless as they appear. There are certain things that we do not know the details of, but it does not mean that those have no purpose in them. It is only our lack of knowledge that the science has not discovered any good use for them so far. We notice that scientists are still working on things that are already known and are making new discoveries every day discoveries. With the advancement in technology, new aspects of already discovered things are being explored.

Hair on human body is one such thing. Besides head, eyebrows and eyelashes, hair on the rest of the body are considered unnecessary and are always unwanted. Every effort is made to get rid of them. Here are some interesting details about human hair on different parts of the body.

1. Body hair work like receptors. Scientists have experimented that people with more body hair are better bedbug detectors. Twenty-nine students were part of this experiment. Arms for half of them were shaved to verify how long it would take to detect bedbugs placed on their arm. The researchers found that body hair enhanced the ability to detect bugs on the body quickly. Thus, the hairs served as motion detectors.

Their colors also vary ranging from black hair to brown.

The liquid does not come down straight to the eye, rather changes its direction due to the hair on the eyebrows and passes from the sides.

15 Interesting Things About Skin That You Didn't Know

Beautiful skin is one of such organs of the body that seems simple but actually performs a lot of functions. Some of them are:

Watermelon has a number of health benefits for all of us to benefit from. A few of the major benefits from watermelon are listed below.

Good for Heart

It increases the amount of arginine, which is an amino acid used in making nitrous oxide, in the body. This oxide help to relax blood vessels. This would help avoid strokes and heart attacks.

Watermelon helps the kidney filter body fluids in a better way. Major portion of the watermelon pulp is water that actually help to remove any foreign particles along with urine. It also helps remove kidney stones. Watermelon pulp contains potassium that helps to remove toxic elements from the body through urine. Thus, maintains a healthy uric acid level in the blood.

Helps Hydration

As major part of the watermelon pulp is water, it thus help to maintain required amount of water in the body, thus helping to avoid de-hydration. This is particularly helpful in hot days of summer when water requirements of our body increase, as most of it is lost through sweating.  Skin remains fresh and glowing if the required water level in the body is maintained.

Weight Control

Keeping in view our desire, nature has kept the calorie count to a lower level in watermelon. Thus, the regular use can help us control or weight.

Is Time really moving fast these days?

We often hear people asking to finish up things quickly because the time left is very short and there are many things yet to be done. I often wonder how this can happen that we have more work to do but we are all short of time. I remember well my childhood when the days used to be too long. We did a lot of things during the whole day even then it didn’t end. We used to sleep during noon, mostly for the time to pass. Things seem changed these days. As soon as we get up early in the morning, a series of activities starts and continues till evening. We are so much absorbed in these activities that we seldom realize that the whole day has passed. Evening comes and then the night and one cycle is completed. It goes on the same way next day and again the next one. Days are continuously turning into weeks, weeks into months and years. It looks like the world clock has gained much speed in this era of ours. It passes so quickly that we often wonder how fast the time is moving. Not only our own time zones, but throughout the world, the situation seems identical.

Immortality - The basic instinct for humans

Man has always wished to live forever. In all the action and animation movies, we always see that the protagonist never dies, although he goes through a series of accidents, injuries and hurdles. This idea basically depicts man’s basic desire to live forever in this world. But in real life, we experience that this is not practicable.

People do die when face similar situations as faced by movie actors in the movies. This is because reality is totally different than the imaginary world. We can imagine anything we want. There is no limit.  Movies are actually a depiction of man’s imagination.

Millions of people came to this world since the birth of Adam. Everyone went to hereafter once he completed the life cycle here in this world. Man’s desire to live forever has always been there. He has been trying different ways to increase his age. Then he started doing things he might be remembered for, after his death. This was the way that became very successful for this purpose.

In every age of history, there were some men who are still remembered, not all of people of that age. The reason for this is that they did something different, something unique and something great that has kept them alive so far. This is the only way by which we, despite being mortal, can become immortal beings in this world. We will be remembered for what we do in this world when we are here.

What I learnt from 'Gravity'

‘Gravity’ is a great British–American science fiction thriller and space drama movie. It was directed, co-written, co-produced and co-edited by Alfonso Cuarón, and stars Sandra Bullock and George Clooney as astronauts involved in the mid-orbit destruction of a space shuttle and their effort to return to Earth.

I was amazed to watch this movie. This is indeed a great movie to learn a lot from.  The vastness of outer space is shown along with the importance of earth for us humans. Here are a few lessons that I learnt from this movie.

Gravitational pull is a blessing

While being on earth, we seldom realize the importance of our own weight i.e. gravitational pull of the earth because it becomes quite common in use. We only notice it when we do not have it i.e. in the outer space when it weakens as we move away from the earth. In the absence of this force, life is horrible as is shown in this movie. Therefore, Gravity is one of the numerous blessing by our creator that we seldom realize.

Love and its Types

Love is a force that all people have the ability to recognize regardless of religion, culture or personal experience. Although we don’t fully understand it, it is a part of everyone’s being. It can be defined as a feeling of strong connection and attachments which are persuaded by extreme delight and admiration, dedication and devotion to each other along with affection and tenderness.

Types of Love

Love can be categorized in three types.

Eros love – known as “erotic love”. It is based on strong feelings toward another. It usually occurs in the first stages of a man-woman “romantic” relationship. Eros is the word for sexual attraction or lust. It is quite simply, the urge to merge. It is generally dependent on the senses. It can come on quite suddenly and leave just as suddenly. This love is based more on physical traits. Say a person says he has “fallen in love” for a woman, because “she looked like an angel”. Or a woman “falls in love” for a guy because he is intelligent, has good breeding, etc. The weakness with this type of love is obvious. It is based more on “self-benefit”, of what can benefit you rather than the other person. The fact is that love by feelings alone cannot be called “true love” simply because they do not know each other that much yet. Two people feel this strong emotional attraction towards one another, though they barely really know about each other’s personalities. A person usually puts her/his best foot forward, showing only her/his good side. In order to be sure if “true love” exists, two people must know and accept each others’ good and bad traits. It is love that is untested by hardships, and therefore may or may not last in the long-term. It may or may not develop into a higher form of love – philos love. Eros love can only succeed in the long-term if it progresses into a higher form of love. Otherwise, it will not last. The romantic feeling common in “eros love” is natural, and an important part of a relationship between a man and a woman. Romance also plays a role in strengthening the bonds, especially at the start of a relationship. What we need to be careful of is assuming a relationship must be “real love” just because it is romantic, because all we feel is happiness. As with most anything in life, we must learn to use both our heart and mind to judge if something is real.

Media has romanticized this type of love too much. Common people are carried away from reality and are lost in imaginations. When they try to practice their imaginations in real life, it creates a lot of problems because reality is different from what is shown in the media. Based on this love, a new term is formed in western culture – single parent- though parents are always two. When both the individuals get all the physical benefits of each other, they separate and one has to take care of the kids. He/she is then called a single parent. This is the reason this type of love is highly discouraged in eastern culture.
