When it comes to living to the ripe old age of 100, good genes help but don’t tell the full story. Where you live has a significant impact on the likelihood that you will reach centenarian age, suggests a new study conducted by scientists at Washington State University’s Elson S. Floyd College of Medicine.
Published in the International Journal of Environmental Research and Public Health and based on Washington State mortality data, the research team’s findings suggest that Washingtonians who live in highly walkable, mixed-age communities may be more likely to live to their 100th birthday. They also found socioeconomic status to be correlated, and an additional analysis showed that geographic clusters where the probability of reaching centenarian age is high are located in urban areas and smaller towns with higher socioeconomic status, including the Seattle area and the region around Pullman, Wash.
As a senior, I want to stress to you that we seniors are more vulnerable to dehydration than our younger associates.
The hot summer months are upon us, but sweating in the sun is not the only factor that raises risk for dehydration. This potentially dangerous drop in body fluid affects everything from blood pressure to the brain, so knowing the causes, signs, and symptoms of dehydration—as well as how to avoid it—is critical.
Dehydration Basics: Any situation that involves either not taking in enough fluid or losing too much fluid can cause dehydration. “We don’t drink enough if fluids are unavailable, or if we lack an adequate thirst response,” says Roger Fielding, PhD, director and senior scientist at the Nutrition, Exercise Physiology, and Sarcopenia Laboratory at Tufts’ Human Nutrition Research Center on Aging. “We lose fluid through sweat, diarrhea, vomiting, or blood loss. Medications like diuretics (water pills), or medical conditions like uncontrolled diabetes, can also cause too much water to leave the body. These factors, alone or in combination, can lead to dehydration.”
Older adults with depression may be at much higher risk of remaining depressed if they are experiencing persistent or worsening sleep problems, according to a study from researchers at Johns Hopkins Bloomberg School of Public Health.
The researchers, who published their findings online April 30 in the journal Sleep, analyzed data from almost 600 people over 60 years old who visited primary care centers in the Northeast U.S. All patients met clinical criteria for major or minor depression at the outset of the study.

This guide focuses on cognitive health and what you can do to help maintain it. The following steps can help you function every day and stay independent—and they have been linked to cognitive health, too.
A study just released by Columbia University Mailman School of Public Health researchers is reporting a blood-DNA-methylation measure that is sensitive to variation in the pace of biological aging among individuals born the same year. The tool—DunedinPoAm—offers a unique measurement for intervention trials and natural experiment studies investigating how the rate of aging may be changed by behavioral or drug therapy, or by changes to the environment. Study findings are published online in the journal e-Life.
“The goal of our study was to distill a measurement of the rate of biological aging based on 12 years of follow-up on 18 different clinical tests into a blood test that can be administered at a single time point,” says lead author Daniel Belsky, PhD, assistant professor of epidemiology at Columbia Mailman School and a researcher at the Butler Columbia Aging Center.
I have written repeatedly about the benefits of walking, calling it the ‘Cinderella of the exercise world.’ Now, according the the National Institutes of Health (NIH), it seems that quantity equals quality in walking.
UNIGE researchers have shown that the decline in cognitive abilities after 50 years of age results in a decline in physical activity, and that – contrary to what has been suggested by the literature to date – the inverse relationship is much weaker.
Someone dies somewhere in the world every 10 seconds owing to physical inactivity – 3.2 million people a year according to the World Health Organization (WHO). From the age of 50, there is a gradual decline not just in physical activity but also in cognitive abilities since the two are correlated. But which of them influences the other? Does physical activity impact on the brain or is it the other way around? To answer this question, researchers from the University of Geneva (UNIGE), Switzerland, and the NCCR Lives Swiss National Center of Competence in Research used a database of over 100,000 people aged 50-90 whose physical and cognitive abilities were measured every two years for 12 years. The findings, which are published in the journal Health Psychology, show that – contrary to what was previously thought – cognitive abilities ward off inactivity much more than physical activity prevents the decline in cognitive abilities. All of which means we need to prioritize exercising our brains. Continue reading →
Healthy aging researchers at Flinders University say certain characteristics of mindfulness seem more strongly evident in older people compared to younger people – and suggest ways for all ages to benefit.
“This suggests that mindfulness may naturally develop with time and life experience,” says behavioral scientist Associate Professor Tim Windsor, who co-authored a recent study based on an online community survey of 623 participants aged between 18 and 86 years. Continue reading →
Conventional wisdom at the time held that the more animals were fed, the better they’d fare. But McKay noticed something different: Long after the well-fed rats began to show signs of aging, those on a nutrient-dense but super-low-calorie diet retained a silky sheen to their fur, remained alert and agile and lacked the age-related health problems of their more gluttonous peers. In the end, the calorie-restricted mice also lived about 300 days longer — nearly a third of a lifetime in rat years.
Fast forward to 2020, and studies in everything from fruit flies and worms to monkeys and people have confirmed that sharply restricting calories (by 20-40 percent) while maintaining essential nutrients can fend off age-related diseases and, in some cases, extend lifespan. The problem: People like to eat, so almost no one is willing to do it. And it can be dangerous. Continue reading →
How many times do we have to say it? Eat less; move more; live longer. Here, it is supported by a new study presented at the Association of Academic Physiatrists Annual Meeting in Orlando.
Good exercise habits formed in adolescence correlate positively with exercise habits in adults, and adults with good exercise habits have better physical performance and appropriate body-mass index scores for their age, according to the study.
Regular exercise habits can lead to better physical fitness and mental health in people of all ages. However, research shows that people in the United States and Canada tend to exercise less as their age increases, and the most significant drop-offs in exercise habits take place during the teenage and early adult years. For this retrospective study, researchers in Taiwan wanted to know if exercise habits formed in adolescence could affect physical fitness in later adulthood, and to assess the relationship between adolescent and adult exercise habits and its influence on later physical fitness.

As a senior citizen who has had family members suffer from dementia and Alzheimer’s Disease, I want to know everything I can about aging and cognition, so this study from Florida Atlantic University piqued my interest.
The neighborhood environment may positively or negatively influence one’s ability to maintain cognitive function with age. Since older adults spend less time outside, the neighborhood environment increases in importance with age. Studies suggest physical aspects of the neighborhood such as the availability of sidewalks and parks, and more social and walking destinations, may be associated with better cognitive functioning. Beneficial neighborhood environments can provide spaces for exercise, mental stimulation, socializing and reducing stress. To date, few studies have examined how the neighborhood’s physical environment relates to cognition in older adults. Continue reading →
Life expectancy — the average number of years a newborn can expect to live — increased in the U.S. by almost 10 years between 1959 and 2016, from 69.9 years to 78.9 years. However, it declined for three consecutive years after 2014, driven largely by a higher mortality rate in middle-aged people of all racial groups.
In the NIA-supported study, researchers at Virginia Commonwealth University analyzed data from the National Center for Health Statistics, the U.S. Mortality Database, and CDC Wonder. They found that from 1999 to 2010, the number of deaths per 100,000 people decreased for all age groups. This decline is attributable to reduced death rates from several specific causes, including heart attacks, motor vehicle injuries, HIV infection and cancer.
Older adults who move more than average, either in the form of daily exercise or just routine physical activity such as housework, may maintain more of their memory and thinking skills than people who are less active than average, even if they have brain lesions or bio-markers linked to dementia, according to a study by Rush University Medical Center.
Women who can exercise vigorously are at significantly lower risk of dying from heart disease, cancer and other causes. The research was presented 7 December at EuroEcho 2019, a scientific congress of the European Society of Cardiology (ESC).
Study author Dr Jesús Peteiro, of University Hospital A Coruña, Spain advised women: “Exercise as much as you can. Fitness protects against death from any cause.”
Exercise is good for health and longevity, but information on women is scarce. Women generally live longer than men, so dedicated studies are needed. This study examined exercise capacity and heart function during exercise in women and their links with survival. The study included 4,714 adult women referred for treadmill exercise echocardiography because of known or suspected coronary artery disease. Continue reading →
I have to admit that I have been seeing items and ads about CoQ10 for years and never paid it much attention. I stumbled across this rundown in Medical News Today and was amazed at its functionality. I thought it would interest you.
CoQ10 is an antioxidant that exists in almost every cell of the human body. CoQ10 deficiency is associated with various medical conditions, such as heart disease, cancer, and Alzheimer’s disease.
Although the body naturally produces CoQ10, some people may benefit from taking supplements. Overall, CoQ10 supplements appear relatively safe and cause few side effects. Supplements are not regulated by the Food and Drug Administration (FDA) for purity or verified for labeling accuracy, so purchase only those products that have been tested by an independent lab.
People who are interested in trying CoQ10 supplements may want to consult a healthcare professional first. Experts do not recommend CoQ10 for people taking blood-thinning medications, insulin, or certain chemotherapy drugs.Continue reading →
