It’s well known that the number of people with Alzheimer’s disease and other dementias is rising… but the speed of the increase is stunning researchers. A study in the journal Lancet Neurology finds that the number of people with dementia around the world has more than doubled since 1990. Researchers estimate that within about 30 years… more than 100 million people will be affected with dementia.
Air pollution is bad for your health… but researchers haven’t been able to quantify just how bad until now. A Danish study in the journal Environment International used advanced models to simulate the effects of pollution on large populations. It shows that cutting city pollution to the level found in the country could increase the lifespan of the average urban dweller by one full year.
And finally… it doesn’t take long to believe your own lies. And the older you are, the less time it takes. A study in the journal Brain and Cognition used EEG’s to monitor brain activity of people purposely telling lies… then telling the truth to the same questions 45 minutes later. Researchers found that people over 60 are much more likely than young people to accept as the truth a lie they had told less than an hour earlier. Apparently, scientists say, telling a lie scrambles the memory so people ultimately accept it as what really happened.
American lifespans have declined for the third year in a row… the first time that’s happened since World War I. A report from the Federal Centers for Disease Control and Preventions finds that a baby boy born today in the United States can expect to live to 76… while the average baby girl can expect a lifespan of 81 years. Researchers blame opioid overdoses… flu deaths… Alzheimer’s disease and suicides for the decline in the American lifespan.
Some women want to have their children as close together as possible, but a new study shows that it’s wise to wait at least a year to get pregnant again. The study in the journal JAMA Internal Medicine finds that waiting a year between the birth of one child and conception of another lowers complications. Women older than 35 have a lower risk of death when they wait … and for mothers under 35, there’s a lower risk for the baby when children aren’t so close together.
And finally… if your desk is a mess, your co-workers probably make negative assumptions about you. A study in the journal Personality and Individual Differences finds that a messy office leads people to think its occupant is more cranky, careless, neurotic and less conscientious than people who have a neater space. Researchers say the finding applies to virtually any personal space.
