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.
When the body starts to produce too much mucus, it accumulates in the lungs among other areas, and the problems begin. Coughing, breathing trouble, chest pain, discomfort in the chest area, and fatigue are some of the symptoms that characterise the build-up of mucus in the lungs.
