The first commercial product to use a microprocessor was the Busicom calculator 141-PF. The 4004 was also used in the first microprocessor-controlled pinball game, a prototype produced by Dave Nutting Associates for Bally in 1974.
3 doctors weighed in: Can post nasal drip result in mucus entering into lungs and accumulating there, or does it just go in stomach ? 3 doctors weighed in Want a second opinion? A little post nasal drip may try to enter the lungs & trigger a strong protective cough. If it went in with any volume you would have a significant pneumonia almost immediately. Most enters the esophagus/stomach & digestive pathway to be broken down over time.
Post-nasal drip occurs when thick or excessive amounts of mucus drip into the back of the throat. The inflammatory substances in the drip coupled with trying to clear the excessive mucus, causes irritation and discomfort. Excess mucus running down the throat may cause hoarseness and lead to a cough. In fact, post-nasal drip is the most common cause of coughs. Other common symptoms include tickling in the throat, snorting, constant clearing of the throat, and difficulty breathing. A sore throat results due to the continual attempts to clear the excess mucus.
