Subjective vs Chronological Age

Subjective age (SA) is how a person sees themselves compared to their chronological or real age (the number of years a person has been alive). A person can feel either younger or older than their chronological age. SA has been highlighted as an important predictor of health outcomes for older adults. Some research supports the notion that SA may be stronger at predicting psychological functioning than a person’s chronological age.

A recent study published in the journal Frontiers of Medicine was the first study of its kind to look at the relationship between brain aging and SA. The study involved 68 healthy participants between 59 to 84 years of age. Using Magnetic Resonance Imaging (MRI) brain scans, researchers recorded data on grey matter volumes (density of cells) in specific brain regions. Grey matter is the “thinking part of the brain” that grows throughout childhood. See this infographic to learn more about grey matter. Regions of the grey matter are involved in muscle control, seeing, hearing, memory, emotions and speaking. Participants filled out subjective age surveys that included the question, “How old do you feel, compared to your real age?” along with tests to evaluate their cognitive function (brain activities that lead to knowledge and include reasoning, memory, attention and language), global health ratings, symptoms of depression and personality traits. The results include:
  • Participants who felt younger than their real age showed larger grey matter volume in the parts of the brain involved in impulse control, hearing/processing sound and verbal/non-verbal communication. Their brains had younger structural characteristics (looked younger), and the differences stayed the same even when other factors were taken into account, such as personality, subjective health (a person’s view of their health), symptoms of depression and cognitive functions. These participants were more likely to score better on a memory test, rate their health as better and were less likely to report symptoms of depression. 
  • Participants who felt older than their real age showed a tendency to have poorer cognitive function and showed greater depressive symptoms. It is possible that those participants who feel older than their actual age may be sensing the aging of their brain because performing cognitive tasks takes more effort. 
These findings suggest that participants who felt older than their age may have faster-aging brain structures, whereas those who feel younger than their age would have better preserved and healthier brain structures. Future studies need to be done over a longer period of time to have a better understanding of this relationship. The authors encourage individuals who feel older than their chronological age to look at their lifestyle habits and activities that contribute to brain aging and take action to improve their brain health.

The results are in line with earlier research finding a relationship between self-perceived age and cardiovascular death. Why might this be the case? One explanation is that people who feel younger will do healthier behaviours. For example, people who feel older may stop being as physically active based on their age – they think that are too old to do an activity. When people feel younger, even if the exercise is seen as challenging, they are less likely to see it as a barrier. If you feel young you may be more likely to eat in a healthful way because you look forward to a healthy future, whereas people who feel older may think that it’s not worth worrying about what they eat because their life is coming to an end.

Researcher Yannick Stephan of the University of Montpellier believes that doctors should be asking all patients about their subjective age, in order to determine who is most at risk of future health problems and to better plan health care. In 2018, he was a co-author of a 2018 study involving data from three large longitudinal studies of middle-aged and older adults. Consistent evidence was found for an association between an older subjective age and a higher risk of mortality. Individuals felt 15 to 16 percent younger on average than their chronological age, but for others who felt older than their chronological age there was a higher risk of mortality (those feeling 8 years older had an 18% higher risk, those feeling 11 years old had a 29% higher risk, and those feeling 13 years older had a 25% higher risk). How to keep a young mindset Dr. Siegel, assistant professor of psychology at Harvard Medical School, suggests taking the following actions:
  • Challenge your brain. Don’t stop learning. Try a new hobby and develop new skills.
  • Be mindful of the present moment as opposed to regretting the past or being negative about aging in the future.
  • Develop a sense of meaning in life. Set goals for your life. Volunteering is a great way to stay connected and improve your community and the lives of others. Self-Management BC offers volunteer opportunities throughout the province. For more information, visit the website. A great quote by Harvard psychologist Dr. Jennifer Moye is “Think of your life as a gift and strive to make each day meaningful.”
  • Follow a healthful lifestyle.
Bottom line: pursue a healthy, active, and engaged lifestyle. Ideally, do things you find enjoyable because those are the activities that you will be able to maintain. Be socially engaged by doing these activities with like-minded people.

Never Too Old for Great Sex

Fine wine and classic cars improve with age, so why not your sexuality? Here’s how to keep your love life healthy and hot for years to come.

 

Sure, sex during midlife and beyond may be different than it was when you were younger. But that doesn’t mean your sex life is destined to be dull or disappointing. On the contrary.

Healthy individuals can remain sexually active and interested well into their 70s, 80s, and 90s, if they choose to. And an active sex life may even help you stay young. Some age-related physical changes may be unavoidable, but these changes don’t have to interfere with sexual intimacy.

The fact is, there’s no one “right” way to experience sex. The way you express your sexuality is shaped by your individuality and your personal circumstances. Whether you’re single or in a relationship, disabled or able-bodied, young or old, think of your sexuality as a unique part of who you are. By taking a more personal, less prescribed approach to sexual intimacy, you allow yourself the freedom to adapt your sex life according to your changing needs.

The first step to maintaining an active, fulfilling sex life is getting to know some of the normal physical changes you’re likely to experience as you get older. The next step is making a few simple adjustments to rev your libido and boost your sex life.

 

Age-Related Change #1: Slower Response Time

As you get older, it may take longer for your body to respond to sexual stimulation. Even if you feel highly aroused, it’s normal for older men to need longer, stronger stimulation to achieve an erection.

Although this is not necessarily a sign of disinterest or a lack of attraction, some men, and their partners, may misinterpret it as such. To avoid misunderstandings, keep the lines of communication open. It may not be easy to talk about sex at first, but in the long run, it will benefit both of you.

What to Do About It

Don’t rush things. Spend more time on foreplay. Explore each other’s body: kiss, caress, lick, or give each other erotic massages. Remember that if your partner is about the same age as you, she may also need more time and stimulation to become sexually aroused.

If you are unable to become aroused on a regular basis, speak with your healthcare provider. There could be a treatable underlying condition causing your difficulties.

 

Age-Related Change #2: Weak Erections and Weakening Pelvic Muscles

Many older men find that their erections are different than they were in their younger years. They may not be as hard, they may not last as long, and the experience of ejaculation may not feel as strong as it used to.

This may be due, in part, to weakening pelvic-floor muscles. Pelvic-floor muscles are responsible for drawing blood to the genitals during sexual activity, affecting erection and orgasm.

What to Do About It

For some men, having sex in the morning, when erections are more likely, helps improve their ability to maintain an erection longer. But keep in mind that penetrative sex isn’t the only way to have great sex. Experiment with different sexual activities to figure out what feels best for you at this time in your life.

You can also strengthen your pelvic muscles by doing Kegel exercises every day. You may have heard that these exercises are just for women, but they can benefit men, too.

 

Age-Related Change #3: Longer Time between Erections

It’s common for older men to experience a longer refractory period — the time it takes until your body’s ready for another erection after you ejaculate. In some cases, the cooling off period may be as long as 12 to 24 hours, or more.

What to Do About It

If you’ve climaxed, but you or your partner isn’t ready for the sexual experience to end just yet, focus on meeting your partner’s needs or on activities that don’t require an erection. For example, you don’t need an erection for oral sex or manual stimulation.

Whatever you do, don’t get stressed worrying about your virility. This is a normal change that comes with aging — not a sign that you’re losing your touch. And you will likely find that the different sexual activities you engage in without an erection are still very pleasurable for you and your partner. Just be sure to reassure your partner that the longer time between your erections is not a reflection of how you feel about her.

Discover 7 Ways to Prevent Alzheimer’s Disease

Good news for people who feel a hint of anxiety every time they forget where they put their keys. More than 50 percent of Alzheimer’s cases may be preventable.

In fact, research suggests that there are seven key healthy lifestyle changes people could make to help prevent Alzheimer’s disease.

 

The Super 7

More research is needed to confirm whether there is a causal link between these seven key risk factors and Alzheimer’s. But there are plenty of other good health reasons to make the following changes:

  1. Get moving.

Inactivity is linked to greater Alzheimer’s risk, so take a daily walk. Walking every day can prevent your brain from shrinking, too.

 

  1. Don’t smoke.

If you do, quit. Smoking may up the likelihood of developing Alzheimer’s disease.

 

  1. Eat more bananas.

The potassium in this cheap and plentiful year-round fruit can help lower your blood pressure by as much as two to three points! And low blood pressure at middle age may help prevent Alzheimer’s disease.

 

  1. Go to bed.

 Getting a good night’s sleep can lower your risk of type 2 diabetes, so get your ZZZs because research suggests that developing type 2 diabetes may up your chances of getting Alzheimer’s.

 

  1. Walk outside.

People who exercise outside — versus at the gym or inside the home — have less depression. That’s good news for the brain, because depression may increase the risk of Alzheimer’s.

 

  1. Take a class.

Higher education is linked to lower rates of Alzheimer’s.

 

  1. Drop a few.

Becoming obese at middle age may be connected to higher Alzheimer’s risk.

 

RealAge Benefits

Learning a new game that requires brainpower can make your RealAge 1.3 years younger.

February 2017

Hello Readers!

Classes are scheduled to begin on March 2nd. It may be a smaller group than I would prefer, but interest is growing as I meet more seniors, and slowly but surely spread the word. I have been offered FREE space at a seniors residence (Chartwell’s Cedarbrooke in Mission) which means I am able to lower the price for the series to the benefit of all!

The space is a choice between two depending on the size of the group. The private dining room is marvellous for a small group and will accomodate tea/coffee and cookies along with the necessary charts etc. The second space is the Theatre which is a very good size for larger groups and has PowerPoint capability along with space for tea/coffee and charts etc. The chairs in the Theatre are a tad too comfortable perhaps, but no-one would complain about that.

At this point I need to settle the approximate count according to active registrations and determine where we will begin – dining room or Theatre. We can take last minute registration but this delays the start of the first session so I prefer pre-registration when possible.

Advertising in a local magazine designed as an information guide is attractive and effective! Writing 200-300 words every other month is not difficult and I can gradually educate the readers as to what we are doing. The magazine is glossy, colouful and each ad can be personalized – all great! My thanks go to Cory Cassel and “WhatsOn” for assistance.

WE ARE ON OUR WAY…

Conscious Aging Workshops

The first set of workshops to be offered in the Fraser Valley of BC begin in 2017!

Starting on January 10th and running every Tuesday afternoon until February 28th, the series will be offered at the local Chamber of Commerce in Mission, BC. Those interested should register soon and if the full fee is paid by January 1st, will receive a 25% discount.

Times are 2 pm to 4 pm, and please note there is limited accessibility. The conference room is on the upper level and accessed around the side of the building by a series of stairs. There is good lighting there.

This is an exciting time…the Mission and surrounding area boasts many active and interested seniors, although younger folks are encouraged to join in!

Charges for shingles Vaccine

Shingles is a painful, debilitating disease. It is also totally preventable.

Please join me in protesting the charge for shingles vaccine in Canada. This a recommended vaccine for older adults as 1 in 3 are likely to get Shingles in older age. Unfortunately many don’t do this due to  either lack of knowledge or the cost charged to them.

In Canada, a patient will pay anything from $150.00 and up for this prescribed prevention. After having their family doctor write the Px, they fill this at a pharmacy and then take the sera to the local Public Health office or back to their doctor’s office for injection.

As this is a highly recommended and effective vaccine, I believe it should be incorporated into the PH vaccine requirements as a FREE service.  Write to  your MLA and MP to apprise them of the above!

Refreshed after a vacation!

Three weeks away, and I return refreshed and renewed. Over the coming week, I will add some material to the Home page, and will continue to work on planning and writing the session material. There will some visual aids to prepare, and while in Panama, I may find a lack of resources. All is not lost as adaptable could be my middle name! Along with a good pal, I hope we can put together a workshop series for the local expats.

Hello world!

Welcome to my ongoing blog….should be about once per week that I will add something to consider.  It may or may not be about aging or the process and reactions, but on the other hand, perhaps I will stick to the topic?
