Now that much of the nation is over the Polar Vortex that came through , I thought it might be a good idea to revisit the idea of surviving and thriving in cold weather. Winter isn’t over yet.
Here are a couple of infographics that spell it out. But, if you want chapter and verse on the subject, please check out my post – Exercising outdoors in cold weather from a while back.
I have written repeatedly about the dangers of soft drinks, both sugary and artificial sweeteners. You can search the subject by punching soft drinks into the S E A R C H box at the right.
Drinking more than one soft drink daily — whether it’s regular or diet — may be associated with an increase in the risk factors for heart disease, Framingham researchers reported in Circulation: Journal of the American Heart Association.
“We were struck by the fact that it didn’t matter whether it was a diet or regular soda that participants consumed, the association with increased risk was present,” said Ramachandran Vasan, M.D., senior author of the Framingham Heart Study and professor of medicine at Boston University School of Medicine. “In those who drink one or more soft drinks daily, there was an association of an increased risk of developing the metabolic syndrome.”
Metabolic syndrome is a cluster of cardiovascular disease and diabetes risk factors including excess waist circumference, high blood pressure, elevated triglycerides, low levels of high-density lipoprotein (HDL “good” cholesterol) and high fasting glucose levels. The presence of three or more of the factors increases a person’s risk of developing diabetes and cardiovascular disease.
I truly believe that old saw “an ounce of prevention ….” So, here are some super positive ideas about protecting yourself from flu this season. Good luck!
I know, I know … you have been waiting all week for these.
I have a bad case of arthritis in both my hands. I use exercise balls, ice packs and CBD oil for temporary pain relief. That is pretty much the only pain I deal with regularly. So, I guess I have a lot to be thankful for as a guy who turns 79 in January. I do realize, however, that many seniors are not so lucky. For them, I recommend these tips from the National Institute on Aging.
Exercising when you’re in pain can be hard. You might think that you should rest until your pain disappears. But depending on the type of pain you’re experiencing, exercise can help reduce your pain and improve your mood.
Most people living with chronic pain can exercise safely. In fact, research has shown that exercise combined with education can reduce one’s risk of lower back pain.
Follow these tips for exercising with pain:

I am guilty of being a coffee lover. I am so bad that when I see someone on TV carrying a cardboard cup of the brew, I am tempted to make some for myself. So, the following was good news for me.
Scientists have now proved that drinking certain types of coffee can be beneficial to brain health, but how does this popular brew support cognitive function? A new study identifies some of the mechanisms that allow coffee to keep mental decline at bay.
While drinking coffee can bring both benefits and risks for a person’s health, a 2016 study from the University of Ulster in Coleraine, United Kingdom, concluded that the health benefits of moderate coffee consumption “clearly outweigh” the potential risks.
Although I like to keep my posts applicable to both men and women, I ran across this article down under and thought you might find it worthwhile reading as it applies to healthy brains.
We’re all living longer, and for many women our older years are our happiest.
Maintaining brain health is key to joining these lucky people living a long, happy and healthy life. But for many women, it’s the slow creep of dementia that leads to the demise of their health, and quality of life.
Two thirds of people living with dementia are women, and the Australian Bureau of Statistics confirms it is now the leading cause of death for women.
Yet there are few studies of how dementia progresses in women.
Two recent studies from the landmark 20-year Women’s Healthy Ageing Project at the University of Melbourne shed light on which women are most at risk of developing dementia, and how we can get in early to prevent or delay the disease.
Their results are timely, coming as the Australian Government considers the best ways to look after women’s health in the future, inviting submissions to its National Women’s Health Strategy for 2020 – 2030.
In research published in Brain Imaging and Behaviour, researchers found that a woman’s volume of grey matter in their brain at the age of 60 predicts their memory performance at 70.
Grey matter is the part of the brain that is controlled by the nerve cell bodies and it’s where the real processing happens, including speech, hearing, feelings, seeing and memory. White matter allows communication to and from grey matter areas, as well as between grey matter and other parts of the body.
In separate study published in the same journal, they also found that women with normal levels of the ‘good’ cholesterol, called HDL which carries cholesterol from other parts of your body back to your liver, in 1992 had less white matter damage in their brain a decade later when they conducted late-life brain MRI scans and cognitive assessments in 2012.
So, maintaining healthy levels of cholesterol impacts on the structure of the brain directly.
“Taken together, these findings show there are useful neuroimaging biomarkers for the prediction of cognitive decline in healthy older women,” says lead researcher Professor Cassandra Szoeke.
“They build on a growing body of research helping us pick up the warning signs of dementia earlier. In fact just this year the National Institute of Ageing published proposed criteria to diagnose dementia and pre-dementia on biomarkers, like brain scan results and body fluid measures of protein levels.”
A team of scientists has successfully trained a new artificial intelligence (AI) algorithm to make accurate predictions regarding cognitive decline leading to Alzheimer’s disease.
Dr. Mallar Chakravarty, a computational neuroscientist at the Douglas Mental Health University Institute, and his colleagues from the University of Toronto and the Center for Addiction and Mental Health, designed an algorithm that learns signatures from magnetic resonance imaging (MRI), genetics, and clinical data. This specific algorithm can help predict whether an individual’s cognitive faculties are likely to deteriorate towards Alzheimer’s in the next five years.
“At the moment, there are limited ways to treat Alzheimer’s and the best evidence we have is for prevention. Our AI methodology could have significant implications as a ‘doctor’s assistant’ that would help stream people onto the right pathway for treatment. For example, one could even initiate lifestyle changes that may delay the beginning stages of Alzheimer’s or even prevent it altogether,” says Chakravarty, an Assistant Professor in McGill University’s Department of Psychiatry.

They say you can’t teach old dogs new tricks, but new research shows you can teach an old rat new sounds, even if the lesson doesn’t stick very long.
For the record I wrote a post on that damaging cliche about teaching old dogs new tricks. You can read it here – Of cats and dogs and cliches ….
Researchers at the Montreal Neurological Institute and Hospital (The Neuro) of McGill University examined the effects of aging on neuroplasticity in the primary auditory cortex, the part of the brain that processes auditory information. Neuroplasticity refers to the brain’s ability to modify its connections and function in response to environmental demands, an important process in learning.
Plasticity in the young brain is very strong as we learn to map our surroundings using the senses. As we grow older, plasticity decreases to stabilize what we have already learned. This stabilization is partly controlled by a neurotransmitter called gamma-Aminobutyric acid (GABA), which inhibits neuronal activity. This role of GABA was discovered by K.A.C. Elliot and Ernst Florey at The Neuro in 1956. Continue reading
While this blog started with a weight control focus, I soon realized that the answer was in living a healthy life, eating intelligently and exercising regularly. Right in harmony with those physical habits, I found that you can’t overlook the mental side of life and expect to succeed. As a result I have written numerous posts on dealing with stress. So, I was very pleased to run across this work on the subject from Harvard Medical School.
Protect yourself from damaging stress
To better cope with stress, consider how you might minimize factors that make it worse. Here are some tips that can help you better manage stress and hopefully prevent some of the damaging effects it could have on your brain.
Establish some control over your situation. If stress isn’t predictable, focus on controlling the things that are. “Having a routine is good for development and health,” says Dr. Kerry Ressler, professor of psychiatry at Harvard Medical School. Predictability combats stress.
Get a good night’s sleep. Stress can result in sleep difficulties, and the resulting lack of sleep can make stress worse. “Sleep deprivation makes parts of the brain that handle higher-order functions work less well,” says Dr. Ressler. Having healthy sleep habits can help. This includes going to bed and waking up at the same time each day, avoiding caffeine after noon, and creating a relaxing sleep environment.
Get organized. Using strategies to help manage your workload can also reduce stress. For example, each day, create a concrete list of tasks you need to accomplish. This way, your duties won’t seem overwhelming. Making a list also gives you a clear end point so you know when you are done. “Laying tasks out like this helps reduce the feeling that the brain is being bombarded,” he says. It can also help you predict when you are likely to be stressed.
Get help if you need it. Reaching out can help you become more resilient and better able to manage stress, which may ultimately protect your brain health. Earlier intervention may reduce disability caused by stress-related complications later on.
Change your attitude toward stress. “A life without stress is not only impossible, but also would likely be pretty uninteresting — in fact, a certain degree of stress is helpful for growth,” says Dr. Ressler. So, rather than striving for no stress, strive for healthier responses to stress.

I think the mainstream media is making us all into journalists.
Ernest Hemingway famously said, “To be a good reporter you need a built-in shockproof crap detector.”
When I started covering the fast-paced futures markets for Reuters News Service back in the 1960’s that quote resounded in my head on a daily basis. I started my journalistic career on the floor of the Chicago Mercantile Exchange talking to traders about what was happening in the futures markets. In those days, the biggest markets were pork bellies, live cattle, live hogs and shell egg futures. The financial instruments futures hadn’t been created yet.
My qualifications included a degree in finance and several years experience magazine writing and editing.
Reporting markets, you had to remember that everyone you talked to had an agenda (and likely a position in the market). So, I always assumed that the person speaking to me had an axe to grind. When someone told me something bullish on the market, I would search around for a contact likely to tell me the ‘other side.’ That way, my market comments remained balanced and useful to traders.

A comprehensive worldwide study of alcohol use and its impact on health concludes that the safest level of consumption is zero. The Global Burden of Disease Study 2016 has calculated levels of alcohol use and its effects on health during 1990–2016 in 195 countries.
The research, which now features in the journal The Lancet, notes that in 2016, alcohol use was responsible for almost 3 million deaths globally.
Alcohol use was the main cause of death for people aged 15–49 that year, accounting for 12 percent of deaths in men of that age.
“Our findings,” says senior study author Dr. Emmanuela Gakidou, who currently works at the Institute for Health Metrics and Evaluation (IHME) at the University of Washington in Seattle, “are consistent with other recent research, which found clear and convincing correlations between drinking and premature death, cancer, and cardiovascular problems.” Continue reading
This is perfectly in line with our mantra of eat less; move more; live longer. Besides all the health benefits of exercise on the brain and body, Harvard Health Publishing says that it also reduces stress.
How does exercise reduce stress, and can exercise really be relaxing?
Rest and relaxation. It’s such a common expression that it has become a cliche. And although rest really can be relaxing, the pat phrase causes many men to overlook the fact that exercise can also be relaxing. It’s true for most forms of physical activity as well as for specific relaxation exercises.
Exercise is a form of physical stress. Can physical stress relieve mental stress? Alexander Pope thought so: “Strength of mind is exercise, not rest.” Plato agreed: “Exercise would cure a guilty conscience.” You’ll think so, too — if you learn to apply the physical stress of exercise in a controlled, graded fashion.
How exercise reduces stress
Aerobic exercise is key for your head, just as it is for your heart. You may not agree at first; indeed, the first steps are the hardest, and in the beginning, exercise will be more work than fun. But as you get into shape, you’ll begin to tolerate exercise, then enjoy it, and finally depend on it. Continue reading
