Lyric discussion by Imani110 

It could be applied to aging baby boomers who used to protest the government (You were so tired, happy, bring down the government, they don't, they don't speak for us) who have resignated themselves to high-stress jobs where they are subjected to heart disease or exposed to dangerous chemicals that are killing them (a job that slowly kills you), eating foods that clog their arteries and smoke and drink so that their body is full of poisons (A heart that's full up like a landfill), and they are slowly coming down with cancer, strokes, and heart attacks (some cancers have symptoms of bruises that don't go away and heart attacks and strokes can be brought on by blood clots blocking blood vessels and don't move), so they deal with businesses that poison the air (I'll take the quiet life, a handshake of carbon monoxide) such as the automobile industry. No longer arguing or protesting (Silent, silent). They may be on their death bed with a terminal disease caused by their lifestyle of the aforementioned or it could be their last time mentioning their dissent before taking in a life of pure acquiescence (This is my final fit, my final bellyache). They trade in the thrill and flavor of their life for the security of assimilation and in exchange for acceptance they get their house in the suburbs complete with a yard and 2.5 children (Such a pretty house, such a pretty garden). And they don't want any stirring up of their past excitement (No alarms and no surprises, please).

Genius interpretation.

Indeed amazing.Completely changed my view on the song.

Definitely, one of the better interpretations I've seen on this site
