"Alzheimer disease"

In our daily life, many people have the habit of digging their nostrils, often unconsciously. A recent study by researchers at Griffith University showed that a bacterium could enter the brain of mice through the olfactory nerve of the nose, where it produced the sign of Alzheimer's disease. That is to say, you like to pick your nose when you are young, and you will have Alzheimer's disease when you are old.
