Consuming one’s dried nasal discharge is officially known as mucophagy. It’s not advisable. Sticking one’s finger into one’s nose can introduce infectious materials or pass them along to others. It can also damage tender nasal tissues.
In 2013, a Canadian researcher proposed the practice evolved because it’s an immune system booster, but peers disagreed, noting that most nasal mucus is swallowed and never makes it to booger status.We tend to pay more attention to contagious diseases like COVID, tuberculosis and AIDS, which infect tens of millions of people annually and kill millions. But noncommunicable diseases take far more lives each year.
For example, cardiovascular diseases, including heart disease and stroke; cancer; diabetes; chronic respiratory diseases; and mental illness cause nearly three-quarters of deaths in the world, killing 41 million people annually. Every year, 17 million people under age 70 die of NCDs, 86 percent of whom live in low- or middle-income countries.
The good news is that most NCDs are linked to preventable risk factors, such as tobacco use, unhealthy diets, harmful use of alcohol, physical inactivity and air pollution. It’s estimated that interventions known to work could avert at least 39 million NCD deaths.In 2021, Google paid $2.1 billion to acquire Fitbit, who makes the wearables that track things like daily step totals and heart rate.
