STOP spitting in street walls and in all public places...
Spreading of Disease :
Saliva hosts a variety of diseases and infections. Spit contains your DNA, thus autoimmune diseases and bacteria are highly contagious in spit, as spit serves as a transit vessel from one host to the next. Spit that carries such infections must penetrate the body somehow and reach the bloodstream such as via an open sore, mouth or even an eye, in order to become deadly. Viruses such as meningitis are also easily transferable through spit. Other germs, such as the common cold and influenza, are significantly prevalent diseases spread by saliva.
People who use chewing tobacco and spit are also posing specific dangers to themselves and hose around them.70 percent of people who use chewing and spitting tobacco get mouth sores, cracking and bleeding lips and gums, receding gums (which can eventually make your teeth fall out), increased heart rate, high blood pressure, and irregular heartbeats -- all leading to a greater risk of heart attacks and brain damage (from a stroke)." Chewing tobacco and the saliva within the mouth can cause oral cancer on the lips, tongue, the roof or floor of the mouth, the cheeks, or the gums. The tainted saliva can also send cancer agents into the lining of the stomach, esophagus and bladder.
So stop spitting and keep our society clean and safe ... THANK YOU !!!
