University of Chicago Medicine finds that sudden loss of smell caused by COVID-19 is as significant a risk factor for the Alzheimer's gene as carrying the APOE-E4 gene itself. The study also revealed a physical connection between the nose and the brain, leading to the buildup of protein tangles and plaque that can cause neurological blockages.
Chlamydia pneumoniae, a dangerous bacteria for the brain, can trigger the production of amyloid plaque, which can cause Alzheimer's or dementia. Keeping the mask on not only helps to avoid inhaling particles but also keeps fingers away from the face and, consequently, from the bacteria and germs that can trigger such diseases.
The speaker discusses his use of tools to manage nose and ear hair, and also mentions the term for compulsive nose picking, rhinotillexomania.
Nose picking in public is more socially acceptable in the US than in Japan, where blowing your nose in public is seen as a bigger social faux pas. The habit potentially stems from childhood and can be acceptable if done discreetly.
Chuck and the host discuss the taboo subject of nose picking and how it is a common human activity. They also mention the rewarding feeling of the first nose blow in the morning.
