U.S. life expectancy fell by 2 yrs in 2020, sharpest drop among high-income peers
2022-04-14
(Reuters) - Life expectancy in the United States fell by nearly two years in 2020 to about 77 years amid the COVID-19 pandemic, the sharpest drop compared to 19 other high-income countries, according to a recent analysis.

Americans, on average, had a life expectancy of 76.99 years in 2020, down from 78.86 years in 2019, according to the study, which looked at national death and population counts in 2019 and 2020, as well as provisional data for 2021 to calculate mortality rate ratios.

The decline of 1.87 years in life expectancy for 2020 was far higher than the mean reduction of 0.57 years in 19 peer countries, including Canada, France, Germany, Denmark and South Korea. No country experienced a decrease as steep as that of the United States, according to the analysis, which was published as a preprint on the medRxiv website.

U.S. COVID-19 mortality and excess deaths were among the highest in the world and the virus was the third leading cause of death in the United States in 2020, after heart disease and cancer.

Based on provisional 2021 data, U.S. life expectancy fell even further last year, to an estimated 76.60 years.

#3  Telomeres be fraying. Just like the cuffs of me jeans (pun intended) and the flag in high wind. What do I know. I’m not a biologist.

#1  Pehal News - Mystery of why humans die around 80 may finally be solved

The thriller of why humans die at around 80, whereas different mammals dwell far shorter or longer lives, may finally have been solved by scientists.

Humans and animals die after amassing an analogous quantity of genetic mutations, researchers have discovered, suggesting the velocity of DNA errors is vital in figuring out the lifespan of a species.

There are enormous variations within the lifespan of mammals within the animal kingdom, from South Asian rats, which dwell for simply six months, to bowhead whales, which might survive for 200 years.

Previously. specialists have prompt that measurement is the important thing to longevity, with smaller animals burning up power extra rapidly, requiring a quicker cell turnover, which causes a speedier decline.

But a brand new examine from the Wellcome Sanger Institute in Cambridge suggests the velocity of genetic injury may be the important thing to survival, with long-living animals efficiently slowing down their charge of DNA mutations regardless of their measurement.

It helps clarify how a five-inch lengthy bare mole rat can dwell for 25 years, about the identical as a far bigger giraffe, which generally lives for twenty-four.
