What is a shocking fact about the human body?

One of the most shocking facts about the human body is its potential to foster brain-eating amoebas, which can lead to fatal infections. Naegleria fowleri is a type of amoeba found in warm freshwater and soil. It enters the body through the nose and travels to the brain, where it causes a highly lethal infection known as primary amoebic meningoencephalitis (PAM). This infection destroys brain tissue and leads to severe brain swelling. Symptoms typically start within a week of exposure and can include headache, fever, nausea, or vomiting, and progress to more severe symptoms like seizures, hallucinations, or coma. Unfortunately, this infection progresses rapidly, and despite treatment efforts, it is almost always fatal, with a survival rate of less than 3%. This alarming fact highlights the capacity of the human body to be affected by minuscule entities that can have devastating effects.
