Every man produces about a liter per day of saliva. In fact, the amount can vary from half a liter to 2.5 liter to get ada, depending on the production of multiple factors: age, health status, activity (for example, produces more saliva that standing or lying down seated: so do look good from a spitting contest if you do a sedentary job). To get an idea of \u200b\u200bwhat this could mean, say that over of our lives will produce about 30,000 gallons of saliva or at least we hope to produce at least a similar amount. In order to view this material as you can think of a circular pool of 6 m in diameter and several feet deep but is not necessary that we dive into it. We begin and end our life drooling and spend the rest of his life to prevent us from swallowing saliva drool. Saliva has many useful features, without which our lives would be much more difficult. In fact, the saliva lubricates the food easier to swallow, lubricates the walls of the mouth and teeth by facilitating verbal expression (think of what it would mean having to always talk with your mouth dried and mixed), prepare the food for digestion by the enzymes of its attack (before digestion fit in hours) and protects against infection from dental caries and for its antibacterial properties (for personal use is better dell'amuchina). Without saliva, the mouth would have chronically inflamed and infected. Also interesting are the psychological effects of saliva. We spend all day in swallowing saliva but when it comes out of our mouth ceases to be spit saliva and becomes, with all the negative meanings that this term carries. None of you, I hope, would drink a glass instead of swallowing their own saliva during the normal activity of swallowing. Yet it is the same substance. Mysteries of the mind!
If you are unable to vomit spontaneously but you had like, here's the list of what to do: to start a deep breath, close the glottis and open the upper esophageal sphincter (the entrance of the esophagus); lift the soft palate to try to prevent the vomiting there coli from the nose (unless you do not like it), suddenly lowered the diaphragm to create a vacuum in the chest that will cause the ' opening of the esophagus and sphincter, which connects to the stomach. At the same time, you should contract your abdominal nuscoli thus compressing the content stomach that quickly retract the esophagus and passing through the mouth will erupt outside. Done? If there is no give in it is able to train your diaphragm and your stomach and improve the synchronism of the movements. In the meantime you can try with some politicians on television osseravare ours. I get excellent results with a Bassino, North America, with false hair ...
Every man produces 705 milliliters of gas per day through eight episodes of flatulence. Who we owe the discovery? The Center for Human Nutrition at the University of Sheffield in 1991 recruited ten volunteers, equally distributed between men and women who had to live for twenty-four hours with a rubber hose inserted to forty centimeters inside the anus. The tube was connected to a plastic collection bag and held in place with the surgical bandage which guaranteed water resistance of the connections (what you do for science ...). But studies on the subject did not stop here. A luminary of the Minneapolis Veterans Affairs Center has used for the collection of flatulence in the same way-lots of rectal tube developed by the team of Sheffield to study but the smell. Samples of flatulence in this case were taken from the bags with a syringe and delivered to two judges in an environment free of odors pushed the plunger of the syringe held three inches from their noses. Smelling intestinal gas several times the two lucky judges then had to assess the 'smell' linare on a scale from 0 (no odor) to 8 (very unpleasant smell). As you can complain about your job there is always someone doing a worse job ... dell'anlisi The result of that mixture of hydrogen sulfide (rotten egg odor), metantiolo (fetid odor of rotten cabbage) and dimetilsulfide (smell dolciatro typical Loffi, where there is plenty this) that takes the name of fart is as follows: women are the intensity odor significantly higher if they also produce a slightly smaller amount. The next time you feel a lift in unbearable stench, but do not be angry with your friend with that elegant lady who looks at the ceiling with air vague ...
PS Both metantiolo that are extremely flammable hydrogen sulfide. So if you are planning to repeat the experiment, careful to keep the bags away from open flames or heat sources.
