This past year was full of news reports regarding hospitalizations and death rates related to COVID-19, both here in the United States and abroad. As such, one might wonder what impact this disease has had on life expectancy.
Wolf, Masters, and Aaron (2021) estimated life expectancy in the United States, and 16 other democracies, for the years 2010–2018 and modeled life expectancy for 2020. They also broke down the life expectancy data from the United States by race, ethnicity, and sex. The results revealed that life expectancy in the United States fell in 2020 compared to 2018. This decrease was more substantial for men than for women and for those who identified as Black or Hispanic as compared to White. As compared to the average life expectancy of the other 16 democracies, there was a greater decrease in the United States.

While this data is striking, the authors did not examine the cause for the change in life expectancy. While COVID-19 may have been a factor, the authors acknowledge there may have been other factors like limitations in access to healthcare related to the pandemic, as well as mental health, social, and economic issues that affected the change in life expectancy.

When you present one tone to one ear and a second to the other ear, your brain perceives an additional tone. This is the essence of binaural beats.

Who’s Afraid of Snakes?
Research shows that approximately half of the population feel “anxious” about snakes, and a whopping three percent of the population meet the diagnostic criteria for snake phobia (Polak et al., 2016). Is it their skin? Is it that they have no legs and thus slither? Is it the tongue? Is it their ears? Wait—do snakes…
