DID YOU KNOW MOST PEOPLE ONLY BREATHE THROUGH ONE NOSTRIL AT A TIME?

Around 80% of human only breath through one nostril at a time, most people don't notice this, they may simply think we use both at the same time or one of them is there to help the other one when it is blocked by a nasty cold.

Your two nostrils shift their workload back and forth in a delicate manner called the NASAL CYCLE. At any moment, most of the air you breath in travels through just one nostril, while a much smaller amount pass through the other. At some point, the nasal cycle reverses course and the workload is shifted to the other nostril.

The duration of time between nostril switching varies, depending on the individual and various other factors, but each cycle usually lasts from 40 minutes to 4 hours or so. That is why you have intervals of easy breathing even when your nose is block by a nasty cold.

It is thought that the nasal cycle could be the reason that whenever we sleep on our side, we will often switch sides throughout the night, even when we are in a comfortable position. It could just be that our body needs to switch which nostril it is breathing out of, so you feel the urge to roll over to your other side while asleep.

WHY YOUR STOMACH GROWL WHEN YOU ARE HUNGRY

Generally speaking stomach growling, or as the Doctors call it today "borborygmi", is the noise created during a series of  muscle contractions in your stomach and small intestine.

The digestive system is one big long tube that begin from your mouth to your butt. Food gets through this long tube via waves of muscle contractions, called peristalsis. These waves of muscle contraction also help to mix and grind foods, liquid, and digestive juices together. The resulting cocktail is called chyme.

The sound you hear when you stomach and intestines make noise is the result of these muscular contractions mixing and moving the chyme down the tube, as well as pushing any resultant air through your system.

The reason your stomach growl more when you are hungry is that, when your stomach and intestines are empty, it triggers a reflexive generation of contraction waves, even though there is nothing in your stomach that needs to move down. These are meant to clear out all of your stomach contents, including the mucus, any remaining food, bacteria, etc. It's your body's way of cleaning and making sure no food or other things accumulates anywhere along your stomach or intestines.

The movement happens almost at all times, but you don't hear it when the stomach is full. So the less content in the stomach the louder the noise is heard.

In order to avoid stomach growling, one just needs to eat.

A wife accidentally broke her husband's penis by rolling off him while they were having sex - so she could do some online shopping on her phone.

WHY WE SAY "O CLOCK"

Before the invention of the clock, people told time a variety of means, depending on where they were and what references were available.

Generally, the Sun was used as a reference point, with solar time time being slightly different than clock time. Clocks divide time evenly, whereas, by solar time, hour lengths vary somewhat based on a variety of factors, like what season it is.

Thus, to differentiate the fact that one was referencing a clock's time, rather than something like a sun time, as early as the fourteenth century one would say something like, "It is seven of the clock,," which later got slurred down to "seven o' clock" sometime around the sixteenth or seventeenth centuries. In those centuries, it was also somewhat common to just omit the "o" altogether and just say something like "seven clock".

While today with people using clock nowadays to tell time, it isn't necessary in most cases to specify we are referencing time from clocks, but the practice of saying "o'clock" has stuck anyway.

WHY ONIONS MAKE YOUR EYES WATER

Onions when growing absorb sulfur from the soil. When you cut an onion you break up their cells, releasing the content of the cell (enzymes). These enzymes then react with the sulfur, creating amino acid sulfoxides. These, then create the highly unstable propanethiol S-oxide, a volatile sulfur compound which in gaseous state move upwards towards your eyes. When it comes in contact with the moisture in your eyes, it forms Sulfuric acid which causes a burning sensation stimulating your eyes (lacrimal gland) to release more tears to wash away the irritant.

Cooking the onion inactivates the enzyme, so while the smell of cooked onions may be strong, it does not burn your eyes. Also you can keep yourself from crying by refrigerating your onion before cutting it (changes the chemistry inside the onion thereby slowing the reactions) or by cutting it under water.

WHY GETTING KICKED IN THE BALL CAUSES ABDOMINAL PAIN

The testes originally form in the abdomen near the stomach and kidneys. The nerves and blood vessels remain attached in that region, even after the balls drop. So when a guy gets kicked in the balls, the pain involved travels up from each testicle into abdominal cavity, via the spermatic plexus, which is the primary nerve of each testicle, and then to the spine.

In addition to the pain in the stomach area, many men also experience nausea. This is thought to be caused by a huge rush of sympathetic nervous system discharge. So the body's tolerance level for that rush determines whether that person will be someone susceptible to actually vomit when kicked in the nuts.

In other words, getting kicked in the balls results in severe pain in testicles, abdomen, nausea and possibly vomiting.
