Comment of the Week
“Years ago my brother was placed on a drug for high blood pressure. Within two weeks he had a heated disagreement with his neighbor and code enforcement at his home that led to a SWAT team being called. Fortunately one of his neighbors was a cop in the same city; he was able to de-escalate the situation and no one was harmed. The next day my brother realized his outrage about many things had begun after taking the drug. He discontinued it. Three years later his wife was put on the same drug; due to constant arguing, they ended up divorced. They had been high school sweethearts.”
