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.
In the case of a viral infection such as cold or flu, the first stage and also the last stage of the infection cause the production of a clear, thin mucus in the nose or back of the throat. As the body begins to react to the virus (generally one to three days), mucus thickens and may turn yellow or green.
