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
First of all, what is peripheral artery disease (PAD). I have heard about it, but don’t have any first hand knowledge of it.
PAD affects about 8.5 million people in the U.S.; people with PAD have blockages in their arteries that slow or stop the blood flood flow to their legs. As a result, they have pain and difficulty walking even short distances.
Drinking flavanol-rich cocoa three times a day improved walking distance in individuals with peripheral artery disease (PAD), reports a new Northwestern Medicine pilot study.
“The degree of improvement from chocolate was significant and meaningful,” said lead author Mary McDermott, MD, the Jeremiah Stamler Professor of Medicine in the Division of General Internal Medicine and Geriatrics and a Northwestern Medicine physician. “Exercise currently is the most effective medical therapy for PAD. In this study, the benefits from chocolate were comparable to the benefits of exercise.”
I wrote about ‘incremental exercise’ last year in which I enumerated my practice of walking back and forth while waiting for the elevator. You can read it – Incremental exercise – good or bad?
It just got harder to avoid exercise. A few minutes of stair climbing, at short intervals throughout the day, can improve cardiovascular health, according to new research from kinesiologists at McMaster University and UBC Okanagan.
The findings, published in the journal Applied Physiology, Nutrition and Metabolism, suggest that virtually anyone can improve their fitness, anywhere, any time.
“The findings make it even easier for people to incorporate ‘exercise snacks’ into their day,” says Martin Gibala, a professor of kinesiology at McMaster and senior author on the study. Continue reading
Holy crap! I am an octogenarian! I can’t believe it. I don’t feel that old. In fact, having been retired for 20 years now, I can honestly say, I feel better and healthier now than when I was working and in my ’50’s. I rode my bike 25 miles yesterday in Chicago’s balmy 30 degree weather and I plan to do the same this morning. Lucky me!
This is my birthday picture from a few years back. It’s the only one I have that’s decorated. Also, my pup is in it, too.
This is from my birthday blog post last year:
One of the main reasons I feel like I have things so together is this blog. I started writing it in March of 2010 with a partner who has since left for other pursuits. From the beginning, I discovered a focus. At first it was simply trying to keep my weight down. I learned portion control and serving size. This Italian guy was surprised to learn that a “serving” of pasta was not a 10 inch plate heaped with spaghetti noodles smothered in tomato sauce. No, a 200 calorie serving of pasta is about the size of a baseball. Incredibly, that was a revelation to me. I put the information to use. I began to reduce my portions accordingly. I am not going to recount all the lessons I learned in the past nearly 10 years, but if you want to get control of your own weight, check out my Page – How to Lose Weight – and Keep it Off.

This is probably something more appropriate for with first week of January, not the fourth. Better late than never. Johns Hopkins Medicine has some very useful information here.
The new year can be an exciting time, brimming with the promise of fresh starts and new beginnings. It’s also an opportunity to recommit to your health and well-being: Eat better. Exercise three times each week. Drink more water.
Creating these resolutions is easy enough. Sticking to them beyond the month of January, however, is another story. Continue reading
Although I think marathon running, per se, makes too many demands on the body, it appears that marathon training and participating can accomplish some very positive effects. New research led by University College of London (UCL) and Barts Health NHS Trust suggests running a marathon for the first time could have several health benefits.
The study, published by the Journal of the American College of Cardiology, found that for first-time marathon runners, training and completion of the marathon resulted in reductions in blood pressure and aortic stiffening in healthy participants that were equivalent to a four-year reduction in vascular age. The greatest benefits were seen in older, slower male marathon runners with higher baseline blood pressure. Continue reading
In 2011, approximately 20% of both women and men reported doing some form of physical exercise at least once a week. By 2017, that figure had grown only slightly among women — to 25% — but more substantially among men — to 31%.
The trend is positive, researchers noted, but the proportion of physically active working Russians remains below the European average.
The physical activity of Russia’s working population does not meet World Health Organization standards
Boxing Day in Chicago was a wonderful high temperature record setter for us residents.
By the way, are you familiar with the Boxing Day reference? I first encountered it in 1976 when I had just moved to London working for Reuters News Service. I expected to go out and do some shopping on the day after Christmas and was introduced to Boxing Day as celebrated there – a National Holiday. No stores open! Naturally, I couldn’t figure out any reason for the Brits to be wanting to engage in boxing on the day following Christmas. Really seemed like a bad match. Continue reading
Fat is fat, right? Well, no. There is more than one kind of fat.
Visceral fat is stored in a person’s abdominal cavity and is also known as ‘active fat’ as it influences how hormones function in the body. An excess of visceral fat can, therefore, have potentially dangerous consequences. Because visceral fat is in the abdominal cavity, it is close to many vital organs, such as the pancreas, liver, and intestines.
The higher the amount of visceral fat a person stores, the more at risk they are for certain health complications, such as type 2 diabetes and heart disease.
I have written repeatedly about the benefits of exercise on both the body and brain. It turns out that there seems to be a link between loss of muscle mass, sarcopenia, and cognitive decline.
Sarcopenia, the loss of muscle mass, tends to happen naturally with age. So, in older people with sarcopenia, excess body fat may not be readily visible. But hidden fat, paired with muscle mass loss later in life, could predict Alzheimer’s risk, researchers warn.
A recent study — the results of which have been published in the journal Clinical Interventions in Aging — has found that sarcopenia and obesity (independently, but especially when occurring together) can heighten the risk of cognitive function impairments later in life.
The research was conducted by scientists at the Comprehensive Center for Brain Health at the Charles E. Schmidt College of Medicine of Florida Atlantic University in Boca Raton.
“Sarcopenia,” explains senior study author Dr. James Galvin, “has been linked to global cognitive impairment and dysfunction in specific cognitive skills including memory, speed, and executive functions.” Continue reading
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
It’s possible to make healthy choices and still enjoy the holidays. Tufts Health & Nutrition Letter has some useful suggestions.
Celebrations often lead to overindulgence, unhealthy choices, and unwanted weight gain. Here are some tips for keeping holiday meals happy and healthy:
Make new traditions…and update the old: Many holiday dishes are high in added sugars or salt. Consider making new traditions: try roasted string beans with slivered almonds in place of creamy string bean casserole, for example. Or look for recipes that substitute ingredients to “lighten” traditional dishes. Continue reading
Cognitive impairment without dementia (CIND), or mild cognitive impairment, is a condition that affects your memory and may put you at risk for Alzheimer’s disease and dementia. According to the U.S. National Library for Medicine, signs of mild cognitive impairment may include frequently losing things, forgetting to go to events and appointments, and having more trouble coming up with words than other people of your age.
My go-to exercise is biking. My dog comes along when the weather is willing. At 79, everything seems to be working …
Some experts believe that risk factors for heart disease also are risk factors for dementia and late-life cognitive decline and dementia. Recently, researchers examined two potential ways to slow the development of CIND based on what we know about preventing heart disease. They published the results of their study in the Journal of the American Geriatrics Society. Continue reading
As a big fan of walking I was thrilled to learn of this further benefit to the Cinderella of the exercise world. Walking leads to an increase of peripheral visual input, according to a study from the University of Wurzburg.
How do we perceive our environment? What is the influence of sensory stimuli on the peripheral nervous system and what on the brain? Science has an interest in this question for many reasons. In the long term, insights from this research could contribute to a better understanding of diseases such as ADHD and Parkinson’s disease.
The topography of the EEG response (l) and its localization in the brain (r) show visual sensory processing during the walking conditions slow and normal – green and red, and standing – black. The image is credited to Barbara Händel.
Perception and the underlying neuronal activities are usually measured while subjects are sitting or lying, for example while doing magnetic resonance imaging. As a rule, the head is fixed and people are encouraged not to blink. The measurements therefore take place under well-controlled but rather unnatural conditions. Continue reading
“It is important to say that it is never too late to begin exercising. The average participant in our study was around 60 years old at baseline, and improvement in cardio-respiratory fitness was strongly linked to lower dementia risk. Those who had poor fitness in the 1980s but improved it within the next decade could expect to live two years longer without dementia,” says Atefe Tari of the Cardiac Exercise Research Group (CERG) at the Norwegian University of Science and Technology (NTNU).
Tari is lead author of a new study that was recently published in Lancet Public Health, a highly ranked journal in the prestigious Lancet family.
“Persistently low fitness is an independent risk factor for dementia and death due to dementia,” the authors concluded. Continue reading
“The hawk is back.” That’s what we Chicagoans say when temperatures turn cold here. I woke up to 20F degrees the other morning. The second week in November is a bit early for such temps, but if you want to ride your bike, you deal with it. By the way, when temps fall to sub zero, the expression here is, “The hawk is back … and he brought his whole damn family.”
So, winter seems to have come early to Chicago.
Whether you ride a bike or not, I think you will find some useful info here.

a while back had a cleverly written item on Your Outdoor Sports Survival Guide
, by Jason Gay. He aptly describes “the maniacal joy of Survival Season,” and observes “Nobody looks suave playing sports in the freezing cold. If you are doing it correctly, you look a little unhinged and suspicious. Are you going to play golf…or rob the Bank of Alaska?”
