Why is garlic good for the body?

Garlic is good for the body because it contains a substance called Alicin.
Now, everything around us, absolutely everything, is made of molecules: water, glass, hair, lamp, air, paper… Even our body is made up of molecules. 
Just like a glass can break if its surrounding area is too cold or too hot or if it has been hit, molecules can also be destroyed by damage. Our body is made up of millions and millions of molecules. These molecules can get damaged in many ways. For example: people who smoke cigarettes; when the smoke of the cigar enters the smoker’s body, it will damage some molecules. The damaged molecules in the body of a human are called Free Radicals.

Free Radicals are very harmful. They cause aging, heart problems and many other unpleasant symptoms.

Alicin which is a substance in garlic can destroy Free Radicals. This means that along with exercise and a healthy diet, Alicin can help to reduce many diseases and can also reduce the growth of wrinkles and many other signs of aging.

How do sharks breath

Like many other fish, sharks breathe using their gills. Sharks have 5 to 7 gills on each side, just behind their eyes and above their fins. As you might know, humans have two lungs on their chest which takes care of respiration. Gills act similarly to Lungs; except for the fact that sharks absorb the oxygen (O) they need from water (H2O) while humans absorb the needed oxygen (O) through the air (O2).

As the sharks are swimming along, the water (H2O) enters their mouth. Just like the nose of a human, the gills of a shark are holes and water can go through them. So the water which has entered the shark’s body goes through the gills, the gills absorb the oxygen (O), and then the rest of the water goes out through the gills and back into the sea.

This is why some sharks are at all times swimming. They swim all the time to allow water to enter their mouth and oxygen to be absorbed. If they don’t swim and keep the flow of the water, they will suffocate.

Smoking Is Dumb: Young Men Who Smoke Have Lower IQs, Study Finds:

This research, conducted by Prof. Mark Weiser of Tel Aviv University's Department of Psychiatry and the Sheba Medical Center at Tel Hashomer Hospital, focused on 18-21 year old men enlisted in the Israeli Army, in the largest ever study of its kind.

The aim was to find out a relation between cigarette smoking and IQ levels. Choosing to study soldiers had two benefits; one being all the men were considered fit and healthy due to pre-screen tests for Army permission. And the second benefit is knocking away the common thought that most smokers are from poor, uneducated families, as the subjects came from diverse economic backgrounds. 

Out of the approximately 20,000 men, 28 % smoked one or to cigarettes a day, 3 % considered themselves ex-smokers and 69 % said they had never smoked.

The average IQ of a non-smoker in the classified age group is 101; whereas the average IQ of those who smoked was approximately 7 grades lower at 94.

Another interesting find was related to twin brothers. In the subjects which one twin smoked and the other didn't, the whole philosophy of this research is proven; as in twins, the genes are almost identical. The results showed that the IQ levels of the non-smoking twin is slightly higher.

Sleep Right = Sleep Tight

"A good laugh and a long sleep are the best cures in the doctor's book."

Laughing has no limitations or instructions to stick to but a comfortable and healthy sleep requires a few guidelines.
Overall, there are three main postures of sleeping. This essay will discuss a few points about each one.

The conditions of the pillow are important for a comfortable sleep and substantial support of the neck and spine. If the pillow is too high or too low, the neck muscles will be strained, presumably leading to obstructed breathing and snoring and also other symptoms.

Considering physical features and special conditions of individuals Dr. Steven Conway remarks, "There is no such thing as a universal fit when it comes to pillows. Find a pillow that is consistent with the shape and size of your body. If you find yourself sleeping on your side with one hand propped under your pillow, that's a clue that you're not getting the support you need from that pillow".

1) Sleeping sideways:

In this case, the pillow has to be so that the spinal cord aligns horizontally. Placing another pillow under the waist also provides additional support.
2) Sleeping on the back:

In this situation, the height of the pillow should be lower than when sleeping sideways. Also, placing a pillow under the knees provides a rather gentler and steadier situation for the spine and neck. 

3) Sleeping on your stomach:

If you prefer sleeping on your stomach, the pillow is recommended to be flat or the head can directly lie on the mattress. Another pillow under the stomach is also recommended for bonus support.

The three points above, are the correct postures of sleeping and along with other factors (pillow, mattress, ….) can decrease the chances of or relieve the pain of osteoarthritis, hip pain and many other back and neck disorders.

"Many people don't realize the reason for their neck or back pain is literally right underneath them -- it's their mattress and pillow." says Scott Bautch, DC, DACBOH.

If you continue to experience pain and discomfort at night or have difficulty falling asleep, visit your doctor of chiropractic. Doctors of chiropractic are trained to treat spinal problems that can interfere with a restful night's sleep.
