This is great to hear for those younger and wondering about life for those in their 70s and 80s. A total of 6,201 people between 50 and 90 years old were surveyed in this study.From Science Daily:

Love and intimacy in later life: Active sex lives common in the over 70s

Older people are continuing to enjoy active sex lives well into their seventies and eighties, according to new research. More than half (54%) of men and almost a third (31%) of women over the age of 70 reported they were still sexually active, with a third of these men and women having frequent sex -- meaning at least twice a month -- according to data from the latest wave of the English Longitudinal Study of Ageing (ELSA).

It is the first study on sexual health of its kind to include people over the age of 80 and uncovers a detailed picture of the sex lives of older men and women in England, finding that a sizeable minority remain sexually active in their old age. Contrary to popular misconceptions, it finds that overall health and conflicting partnership factors were more closely linked to decreasing sexual activity and functioning, rather than simply increasing age.

Problems most frequently reported by sexually active women related to becoming sexually aroused (32%) and achieving orgasm (27%), while for men it was erectile difficulties (39%).

Chronic health conditions and poor self-rated health seemed to have more obvious negative impacts on the sexual health of men compared to women.Men were more concerned about their sexual activities and function than women and, with increasing age, these concerns tended to become more common. Sexually active women were less dissatisfied with their overall sex lives than men, and also reported decreasing levels of dissatisfaction with increasing age.

The study also found that many septuagenarians and octogenarians were still affectionate towards their partners, with 31% of men and 20% of women reporting frequent kissing or petting. Among those who reported any sexual activity in the past three months, 1% of men and 10% of women reported they felt obligated to have sex.

Finding an increased risk of dementia and Alzheimer's with so many common over-the-counter medications such as Benadryl and  Chlortrimeton (the first generation allergy drug that so many people took for years) was an unpleasant surprise. Note: they found the link with high doses or heavy use (3 or more years). Some examples of common anticholinergics (from Wikipedia) are: atropine, benztropine (Cogentin), chlorpheniramine (Chlor-Trimeton), dimenhydrinate (Dramamine), diphenhydramine (Benadryl, Sominex, Advil PM, etc.), doxylamine (Unisom), hydroxyzine (Atarax, Vistaril), ipratropium (Atrovent), oxybutynin (Ditropan, Driptane, Lyrinel XL), tolterodine (Detrol, Detrusitol), tiotropium (Spiriva), and bupropion (Zyban, Wellbutrin). The message here: only take medications when absolutely needed and for as little a time as necessary. The study was done on older adults, so now the question is: what about children or young adults who take these drugs for years? Is there a similar increased risk later in life? From Medical Daily:

Common Over-The-Counter Anticholinergic Drugs Like Benadryl May Increase Your Risk Of Alzheimer's

Anticholinergic medications span a range of common drugs and include antihistamines, sleep aids, antidepressants, cardiovascular meds, gastrointestinal drugs (for diarrhea, incontinence, diverticulitis, and ulcers), and muscle relaxants. Now, a new study confirms the link between these everyday medications and dementia. Taking anticholinergic drugs at high doses or for a long time may significantly increase your risk for developing Alzheimer's disease and other dementias, say researchers from University of Washington School of Pharmacy.

“If providers need to prescribe a medication with anticholinergic effects because it is the best therapy for their patient, they should use the lowest effective dose, monitor the therapy regularly to ensure it's working, and stop the therapy if it's ineffective,” Dr. Shelly Gray, a professor and director of the geriatric pharmacy program at the UW School of Pharmacy said in a release.

On average, older people take four or five prescription drugs and two over-the-counter drugs each day. Clearly, drugs are an important part of medical care for older people; however, older people are more sensitive to the effects of many pills, including anticholinergics, which block the neurotransmitter acetylcholine and so effect the nervous system. While the drugs are too numerous to mention, those with anticholinergic effects — and these effects are sometimes dependent on the dose include Benadryl, Sominex, Xanax, Ativan, Valium, Luminal, Skelaxin, Limbitrol, and Tavist.

For the current study, the researchers investigated a previously reported link between anticholinergics, both prescription strength and over-the-counter, and dementia by employing more rigorous methods than in the past. Specifically, the researchers conducted a longer follow-up of more than seven years and more accurate use assessment via pharmacy records, which included nonprescription choices. The team tracked nearly 3,500 seniors participating in a long-running study, the Adult Changes in Thought (ACT), a joint project of UW and the National Institute on Aging.

The most commonly used medications in the study, the researchers discovered, were tricyclic antidepressants like doxepin (Sinequan), antihistamines like chlorpheniramine (Chlor-Trimeton), and antimuscarinics for bladder control like oxybutynin (Ditropan). People taking at least 10 mg/day of doxepin, 4 mg/day of diphenhydramine, or 5 mg/day of oxybutynin for more than three years, the researchers estimated, would be at greater risk for developing dementia. Importantly, substitutes are available for some of these drugs.  

While this study is the first to show a dose response — meaning, the more you use anticholinergic medications the greater your risk of developing Alzheimer’s — it also is the first to suggest this higher risk may persist, and may not be reversible, even years after you stop taking these drugs.

Over the past year I have seen a number of studies looking at alcohol consumption and health effects. Overall it seems that the effects of alcohol are complex and frequently result in a J-curve: abstainers have a higher mortality rate or problems, light or moderate drinkers do the best, and then heavier drinkers have the most problems and higher mortality rates. The following two studies support this. From Science Daily:

Drinking moderate amounts of alcohol is linked to reduced risk of heart failure, large study finds

Evidence already exists for the beneficial effects of drinking moderate amounts of alcohol on the risk of developing a number of heart conditions; however, the role it plays in the risk of developing heart failure has been under-researched with conflicting results. Now, a large study of nearly 15,000 men and women shows that drinking up to seven drinks a week in early to middle age is associated with a 20% lower risk of men developing heart failure in the future when compared to people who did not drink at all, and a more modest 16% reduced risk for women.

They defined a drink as one that contains 14g of alcohol, equivalent to approximately one small (125ml) glass of wine, just over half a pint or a third of a litre of beer, and less than one shot of liquor such as whisky or vodka. The study participants were divided into six categories: abstainers (people who recorded having drunk no alcohol at every visit by the researchers), former drinkers, people who drank up to seven drinks a week, or between 7-14 drinks, 14-21 drinks, or 21 or more drinks a week.

From Science Daily:

If you're over 60, drink up: Alcohol associated with better memory

For people 60 and older who do not have dementia, light alcohol consumption during late life is associated with higher episodic memory -- the ability to recall memories of events -- researchers report.

Moderate alcohol consumption was also linked with a larger volume in the hippocampus, a brain region critical for episodic memory. The relationship between light alcohol consumption and episodic memory goes away if hippocampal volume is factored in, providing new evidence that hippocampal functioning is the critical factor in these improvements.

Findings from animal studies suggest that moderate alcohol consumption may contribute to preserved hippocampal volume by promoting generation of new nerve cells in the hippocampus. In addition, exposing the brain to moderate amounts of alcohol may increase the release of brain chemicals involved with cognitive, or information processing, functions.

Although the potential benefits of light to moderate alcohol consumption to cognitive learning and memory later in life have been consistently reported, extended periods of abusing alcohol, often defined as having five or more alcoholic beverages during a single drinking occasion is known to be harmful to the brain.

I feel like I'm posting the same thing over and over as study after study finds the same or similar results. Bottom line: sitting much is bad for health, so get up and move (walks are good). The more you move or exercise, the better for health.

From Science Daily: Sitting for long periods increases risk of disease and early death, regardless of exercise

The amount of time a person sits during the day is associated with a higher risk of heart disease, diabetes, cancer, and death, regardless of regular exercise, according to a review study.

"More than one half of an average person's day is spent being sedentary -- sitting, watching television, or working at a computer," said Dr. David Alter, Senior Scientist, Toronto Rehab, University Health Network (UHN), and Institute for Clinical Evaluative Sciences. "Our study finds that despite the health-enhancing benefits of physical activity, this alone may not be enough to reduce the risk for disease." The meta-analysis study reviewed studies focused on sedentary behaviour.

The authors found the negative effects of sitting time on health, however, are more pronounced among those who do little or no exercise than among those who participate in higher amounts of exercise."The findings suggest that the health risk of sitting too much is less pronounced when physical activity is increased," said Biswas. 

In the interim, Dr. Alter underlines strategies people can use to reduce sitting time. The target is to decrease sedentary time by two to three hours in a 12-hour day...For example, at work, stand up or move for one to three minutes every half hour; and when watching television, stand or exercise during commercials."

Inactivity is more deadly than obesity. From Medscape:

Inactivity More Deadly Than Obesity, Large New Study Finds

Fresh evidence that just a little bit of exercise, such as 20 minutes walking a day, is extremely beneficial — regardless of whether people are overweight/obese or not — has emerged from a large European study.

In fact, the most pronounced reduction in premature death risk was observed among individuals who were normal weight/abdominally lean and "moderately inactive," compared with those of the same build who were completely inactive, which was defined as having a sedentary job with no reported recreational physical activity.

Looking at this another way, the study — in more than 330,000 men and women — showed that twice as many premature deaths may be attributable to lack of physical activity compared with the number of deaths attributable to obesity, the researchers say.

"This is a simple message: just a small amount of physical activity each day could have substantial health benefits for people who are physically inactive," said Dr Ekelund in a statement. "Although we found that just 20 minutes would make a difference, we should really be looking to do more than this — physical activity has many proven health benefits and should be an important part of our daily life," he added.

So they set out to examine the relationship between physical activity and all-cause mortality and to look at whether BMI and waist circumference modified these associations in a large sample of 334,161 men and women followed for more than 12 years... Just under a quarter (22.7%) of participants were categorized as inactive, reporting no recreational activity in combination with a sedentary occupation.

Over the 12 years of follow-up, 21,438 participants died.The greatest reduction in risk for premature death occurred in the comparison between inactive and moderately inactive groupsAll-cause mortality was reduced by 16% to 30% in the moderately inactive group compared with those categorized as inactive, across all strata of BMI and waist circumference.

The authors estimate that doing exercise equivalent to just a 20-minute brisk walk each day — burning between 90 and 110 kcal — would take an individual from the inactive to moderately inactive group and thereby reduce the risk for premature death by this same amount (ie, between 16% and 30%).

The impact was greatest among normal-weight individuals, but even those with higher BMI saw a benefit of physical activity.

This wonderful opinion piece is by Dr. John Mandrola, a cardiologist who also posts on his own blog at http://www.drjohnm.org/ . The bottom line: lifestyle is more important than drugs in preventing heart disease. The following is from Medscape:

Heart Disease and Lifestyle: Why Are Doctors in Denial?

I think and write a lot about the role of lifestyle choices as a treatment strategy. As an endurance athlete, I know that exercise, diet, sleep, and finding balance in life are the key components of success. It is the same in cardiology.

In a randomized controlled trial of primary prevention, no cardiologist would want to be compared against a good physical trainer or nutritionist. We would get trounced. Our calcium scores, biomarkers, pills, and procedures would not stand a chance. The study would be terminated early due to obvious superiority of lifestyle coaching over doctoring—which would blunt the true treatment effect and make us look less bad. (Wink to my epidemiology friends.)

I write a post about new oral anticoagulant drugs or statins or AF ablation, and people pay attention. You see it in the traffic. It's the same story at medical meetings: sessions on drugs and procedures draw the crowds. Late-breaking studies rarely involve the role of exercise or eating well. Exercise, diet, and going to bed on time have no corporate backing. The task of drawing attention to the basics is getting harder, not easier.

And this is our problem. I believe the collective denial of lifestyle disease is the reason cardiology is in an innovation rut. This denial is not active or overt. It is indolent and apathetic. Bulging waistlines, thick necks, sagging muscles, and waddling gaits have begun to look like normal. During the electronic medical record (EMR) click-fest after seeing a patient, I rarely click on "normal" physical exam. The general appearance is abnormal—either overweight or obese.

This is how I see modern cardiology. Our tricks can no longer overcome eating too much and moving too little. We approach health but never get there. If you waddle, snore at night, and cannot see your toes while standing, how much will a statin or ACE inhibitor or even LCZ696 help?

In fact, a reasonable person could make an argument that our pills and procedures might be making patients sicker.

When I started electrophysiology, I mostly treated people with fluky problems. My ablation procedures were on people with supraventricular tachycardia (SVT) due to aberrant pathways. My devices were mostly pacemakers in the elderly—a disease due to aging. These sorts of problems are (mostly) independent of how many sugar-sweetened beverages one drinks.

Now it is different. My practice is dominated by atrial arrhythmia—a disease now recognized as being due (in large part) to excesses of life, such as obesity, high blood pressure, sleep disorders, and overindulgence in alcohol. In other words: unnecessary. I make hundreds of dollars putting a hundred burns in a left atrium for a disease that a poorly paid physical trainer might prevent or treat. This has become cardiology writ large.

But the thing I cannot get over is that I am doctor, not a proceduralist. I am tasked with helping people be well. I fail in that task if I ignore the most effective and safest treatment option. I fail if I take the easy path. The prescription pad is easy. The EP lab is easy. The truth is hard... New anticoagulant drugs are easy. Ablation technology is easy. Statins are even easier. The truth—nutrition, exercise, balance in life—is hard.

Nowadays many medical societies do NOT recommend annual physicals for healthy adults.

From Medscape: Is the Annual Physical Past Its Prime...Again?

Few medical societies still recommend healthy adults undergo annual physicals, and some groups actively recommend against them, yet many physicians continue to offer the visits to their patients. This week, oncologist and health policy expert Ezekiel Emanuel, MD, PhD, has taken the debate to the opinion pages of the New York Times, where he explains again why the formerly prescribed practice should be proscribed. Once again, however, not everyone agrees the healthy patient exam should be a thing of the past.

According to Dr Emanuel, who is vice provost, global initiatives, and chair, Department of Medical Ethics and Health Policy, University of Pennsylvania, Philadelphia, recent estimates say about 45 million Americans will have a routine general physical this year, which he likens to the human equivalent of the 15,000-mile check-up on their cars. "If you estimate the cost of the exam alone conservatively at $100, it's beginning to be a nontrivial amount of money," Dr Emanuel told Medscape Medical News.

And that is before you add in the costs of laboratory panels, follow-up tests, patient anxiety, and the overdiagnosis or overtreatment of conditions that, if left undetected, would never have become clinically significant. "We see this with prostate cancer and thyroid cancer," Dr Emanuel said.

As he writes, "If you screen thousands of people, maybe you'll find tens whose exams suggest they might have a disease. And then upon further tests, you'll find it is really only a few individuals who truly have something. And of those individuals, maybe one or two actually gain a health benefit from an early diagnosis."

From a health-promotion perspective, then, the annual physical exam is of little value, does not reduce morbidity and mortality from acute or serious chronic conditions, and may even lead to unwarranted complacency in "people who just want to make sure," he said to Medscape Medical News.

To support that statement, Dr Emanuel points to evidence from a 2012 Cochrane Collaboration review of 14 randomized controlled trials involving 182,000 people followed for a median of 9 years. The unequivocal conclusion of the analysis was that routine general check-ups, not prompted by actual symptoms, are unlikely to yield much benefit. No matter what screenings and tests were administered, annual physicals did not reduce mortality overall or specifically from the big killers, cancer and heart disease.

More recently, data from the Danish Inter99 study, a large, randomized trial, supported the conclusion that general check-ups are ineffective. The community-based trial of almost 60,000 adults aged 30 to 60 years, with screening for ischemic heart disease risk and repeated lifestyle interventions over the course of 5 years, found no effect on ischemic heart disease, stroke, or mortality at the population level after 10 years.

Dr Emanuel noted that the US Preventive Services Task Force does not recommend routine annual check-ups, and the Canadian Task Force on the Periodic Health Examination has recommended against the practice since 1979. "Those who preach the gospel of the routine physical have to produce the data to show why these physician visits are beneficial," he writes in his article.

So far, physicians' response to his op-ed piece "has been 90% supportive. They've looked at the data and are not convinced by the data [of the annual check-up's value]," he told Medscape Medical News... Many physicians, however, stand by an annual visit to the consulting room, including Peter C. Galier, MD, professor of medicine, University of California, Los Angeles, School of Medicine. "You can manipulate the data from these meta-analyses any way you want, but when you see patients regularly, you get important information that you may never get until there's an acute problem," he said.

Exercise is the Fountain of Youth? Note that they could not come up with a biomarker of aging in these active people. From Medical Xpress;

Exercise allows you to age optimally

Staying active allows you to age optimally, according to a study by King's College London and the University of Birmingham. The study of amateur older cyclists found that many had levels of physiological function that would place them at a much younger age compared to the general population; debunking the common assumption that ageing automatically makes you more frail.

The study, published in The Journal of Physiology, recruited 84 male and 41 female cycling enthusiasts aged 55 to 79 to explore how the ageing process affects the human body, and whether specific physiological markers can be used to determine your age.

Cyclists were recruited to exclude the effects of a sedentary lifestyle, which can aggravate health problems and cause changes in the body, which might appear to be due to the ageing process. Men and women had to be able to cycle 100 km in under 6.5 hours and 60 km in 5.5 hours, respectively, to be included in the study...Participants underwent two days of laboratory testing at King's. For each participant, a physiological profile was established which included measures of cardiovascular, respiratory, neuromuscular, metabolic, endocrine and cognitive functions, bone strength, and health and well-being. Volunteers' reflexes, muscle strength, oxygen uptake during exercise and peak explosive cycling power were determined.

The results of the study showed that in these individuals, the effects of ageing were far from obvious. Indeed, people of different ages could have similar levels of function such as muscle strength, lung power and exercise capacity. The maximum rate of oxygen consumption showed the closest association with age, but even this marker could not identify with any degree of accuracy the age of any given individual, which would be the requirement for any useful biomarker of ageing.

In a basic, but important test of function in older people, the time taken to stand from a chair, walk three metres, turn, walk back and sit down was also measured. Taking more than 15 seconds to complete the task generally indicates a high risk of falling. Even the oldest participants in the present study fell well below these levels, fitting well within the norm for healthy young adults.

Overall, the study concluded that ageing is likely to be a highly individualist phenomenon...The main problem facing health research is that in modern societies the majority of the population is inactive. A sedentary lifestyle causes physiological problems at any age. Hence the confusion as to how much the decline in bodily functions is due to the natural ageing process and how much is due to the combined effects of ageing and inactivity."

"In many models of ageing lifespan is the primary measure, but in human beings this is arguably less important than the consequences of deterioration in health. Healthy life expectancy - our healthspan - is not keeping pace with the average lifespan, and the years we spend with poor health and disabilities in old age are growing."

Emeritus Professor Norman Lazarus, a member of the King's team and also a cyclist, said: "Inevitably, our bodies will experience some decline with age, but staying physically active can buy you extra years of function compared to sedentary people. Cycling not only keeps you mentally alert, but requires the vigorous use of many of the body's key systems, such as your muscles, heart and lungs which you need for maintaining health and for reducing the risks associated with numerous diseases."

From Science Daily:

More whole grains associated with lower mortality, especially cardiovascular

Eating more whole grains appears to be associated with reduced mortality, especially deaths due to cardiovascular disease (CVD), but not cancer deaths, according to a report.

Whole grains are widely recommended in many dietary guidelines as healthful food. However, data regarding how much whole grains people eat and mortality were not entirely consistent.

Hongyu Wu, Ph.D., of the Harvard School of Public Health, Boston, and coauthors examined the association between eating whole grains and the risk of death using data from two large studies: 74,341 women from the Nurses' Health Study (1984-2010) and 43,744 men from the Health Professionals Follow-Up Study (1986-2010). All the participants were free of cancer and CVD when the studies began.

The authors documented 26,920 deaths. After the data were adjusted for potential confounding factors including age, smoking and body mass index, the study found that eating more whole grains was associated with lower total mortality and lower CVD mortality but not cancer deaths. The authors further estimated that every serving (28 grams/per day) of whole grains was associated with 5 percent lower total mortality or 9 percent lower CVD mortality.

Again, the same message of what are healthy habits to prevent heart attacks and heart disease: not smoking, a normal body mass index, physical activity of at least 2.5 hours per week, watching seven or fewer hours of television a week, consumption of a maximum of one alcoholic drink per day on average, and a diet in the top 40 percent of a measure of diet quality.From Medical Xpress:

A healthy lifestyle may prevent heart disease in nearly three out of four women

A new study that followed nearly 70,000 women for two decades concluded that three-quarters of heart attacks in young women could be prevented if women closely followed six healthy lifestyle practices.

The study, published today in the Journal of the American College of Cardiology, followed participants in a study of nurses established in 1989, which surveyed more than 116,000 participants about their diets and other health habits every two years. Researchers from Indiana University, the Harvard School of Public Health, and Brigham and Women's Hospital analyzed data on 69,247 of the participants who met the requirements for their study. "Although mortality rates from heart disease in the U.S. have been in steady decline for the last four decades, women aged 35-44 have not experienced the same reduction," said Andrea K. Chomistek, ScD, a researcher from the Indiana University School of Public Health-Bloomington and lead author of the paper.

Healthy habits were defined as not smoking, a normal body mass index, physical activity of at least 2.5 hours per week, watching seven or fewer hours of television a week, consumption of a maximum of one alcoholic drink per day on average, and a diet in the top 40 percent of a measure of diet quality based on the Harvard School of Public Health healthy eating plate.

During 20 years of follow-up, 456 women had heart attacks and 31,691 women were diagnosed with one or more cardiovascular disease risk factors, including type 2 diabetes, high blood pressure or high levels of blood cholesterol. The average age of women in the study was 37.1 years at the outset; the average age of a heart disease diagnosis was 50.3, and the average age for diagnosis with a risk factor for heart disease was 46.8.

Researchers found that women who adhered to all six healthy lifestyle practices had a 92 percent lower risk of heart attack and a 66 percent lower risk of developing a risk factor for heart disease. This lower risk would mean three quarters of heart attacks and nearly half of all risk factors in younger women may have been prevented if all of the women had adhered to all six healthy lifestyle factors, the authors said.

Independently, not smoking, adequate physical activity, better diet, and lower BMI were each associated with a lower risk for heart disease. Women who consumed moderate amounts of alcohol—approximately one drink per day on average—saw the lowest risk compared to those who did not drink at all and those who drank more.
