People say that the elevator doesn't go all the way to the top or that someone's elevator doesn't go all the way to the top to mean that someone is stupid or mentally ill. I get the feeling his elevator doesn't go all the way to the top.
Too much mucus buildup in throat is most often due to excessive post nasal drip. This can be caused by allergies, flu, and the common cold. The phlegm that accompanies an infection can hang around long-term. It usually clears up within 4 to 6 weeks, but for some people the problem can drag on for months.
If you have chronic mucus production, that could be a sign of a chronic infection in the lungs. Mucus is produced by the lungs in order to trap dirt and harmful particles from entering the lungs. The reason that colds and infections can cause mucus production is because they can cause inflammation and damage of the lining of our lungs, causing increased secretion of mucus and sloughing of airway cells.
