By 2060, almost a quarter of all U.S. residents will be over age 65, and life expectancy will reach an all-time high of 85 years, according to new reports the U.S. Census Bureau released Thursday.The growth in life expectancy in the U.S. over the next four decades is expected to be slower than it was in the four previous decades. Between 1970 and 2015, life expectancy rose by almost 8 years, but it’s only predicted to rise about 6 years between 2017 and 2060. That’s because in the latter half of the 20th century, there were decreases in infectious diseases and cardiovascular deaths, increases in vaccinations as well as the promotion of exercise and anti-smoking campaigns.Looking forward, “the prevalence of preventable health risks — such as smoking, obesity, and, more recently, opioid-related overdoses — hinders overall population health and contributes to slowed gains in life expectancy,” according to the report which uses the U.S. Census Bureau’s 2017 National Population Projections.Although women are still projected to live longer than men by 2060, as they do now, life expectancy is expected to grow larger for men than woman. While all racial and ethnic groups are expected to have gains in life expectancy, the biggest ones are projected to be for black men, American Indian men and Alaska native men, according to the report.The U.S. is expected to grow by almost a quarter in the next four decades, from about 332 million people today to 404 million people by 2060. By 2028, the percentage of foreign-born people will be 14.9%, the highest level since 1850, according to the Census Bureau.But growth hinges on U.S. immigration policy, according to the Census Bureau.With high levels of immigration, defined as an increase of 50% above last decade’s levels, the U.S. population could grow to 447 million people by 2060. With no immigration, the United States would lose population after 2035, and the country’s population would decline to 320 million by 2060, according to the Census Bureau.Immigration also will determine the nation’s diversity by 2060, said demographer William Frey of The Brookings Institution.By 2045, whites will represent less than half of the U.S. population under current projections, but that could speed up to 2040 under the high immigration scenario, he said.“If immigration was stopped, then we will stay majority white until 2060 but barely at 51.1 percent,” Frey said in an email. “But the story is different for the young under age 30 population.”For those under age 30, the population becomes “minority white” in 2022 with the high immigration scenario. Under current projections, it crosses that threshold in 2024. Without immigration, whites under age 30 will be in the minority by 2032, Frey said.Starting in 2030, international migration will be the biggest driver of population growth in the U.S., exceeding natural increases.The country’s population growth will slow down over the next four decades, growing by about 2.3 million people a year through 2030. But it will then decrease to about 1.8 million a year from 2030 to 2040, and even further to about 1.5 million people a year from 2040 to 2060, according to the projections.___Follow Mike Schneider on Twitter at 3243

As computers, tablets and cellphones have become a growing part of our lives, the exposure to blue light emitted from these devices increases. While blue light exposure has been known to cause strain in eyes, Oregon State University researchers studied the effect of blue light exposure on aging. Based on to their findings, exposure to blue light could cause aging to accelerate. For their study, researchers used common fruit flies and exposed them to 12 hours of blue LED light and 12 hours of darkness. To compare, researchers kept a group of flies in total darkness, as well as a group of flies that were exposed to light that had the blue wavelengths filtered out. The researchers said they chose fruit flies because their cellular and developmental mechanisms are similar to humans.The researchers said that flies exposed to blue LED light sustained damage to their retinal cells and brain neurons and had impaired locomotion. Even more stunning, some of the flies, which exhibited some brain damage, were mutants that did not develop eyes."The fact that the light was accelerating aging in the flies was very surprising to us at first,” said Jaga Giebultowicz, a professor of integrative biology at Oregon State. “We’d measured expression of some genes in old flies, and found that stress-response, protective genes were expressed if flies were kept in light. "We hypothesized that light was regulating those genes. Then we started asking, 'what is it in the light that is harmful to them,' and we looked at the spectrum of light. It was very clear cut that although light without blue slightly shortened their lifespan, just blue light alone shortened their lifespan very dramatically.” 1708

As more states legalize marijuana, more law enforcement efforts are put in place to keep high drivers off the roadways.The State of Missouri is one that is cracking down on people driving after using pot. The Missouri Department of Transportation announced this week it will have a blitz on April 19-20.Those dates have been chosen because the number 420 is a code used by cannabis enthusiasts who celebrate the drug on April 20. In 2018, MoDOT reported 78 people were killed and 142 seriously injured in traffic crashes with at least one-drug impaired driver. 572
