There is an age when we begin to look at our parents differently. We no longer just see them as the people who took care of us, but as a kind of uncomfortable mirror of the future.
Perhaps you remember your father’s knee, always swollen. Or the sciatica that shot down his leg and made him stand up from his chair slowly. Perhaps your mother started having small urine leaks after childbirth and ended up normalizing it for years. Or maybe what distresses you most is the memory: those first repetitions, the lapses, the feeling that something was slowly fading away.
And then the question appears that we don’t always dare to say out loud: if my parents aged like this, am I on the same path?
The short answer is not necessarily. Genetics play a role, but they do not completely determine how you will age. Having inherited a predisposition does not mean your fate is sealed. Your parents aged with the information, tools, and habits of their time. You have much more information at your fingertips.
In this article, we are going to look at what role genes really play, which diseases have a significant hereditary component, how much weight habits and environment carry, and what decisions can help you reach your later years with more autonomy and quality of life.
What are we really afraid of?
According to research by the Columbares Foundation presented by HelpAge Spain, more than 52% of people in Spain say they are afraid of aging. However, this fear is not really about getting older; rather, it centers on four specific pillars:
1. Loss of physical autonomy
Old age is associated with frailty, less autonomy, and the need for help with basic activities. It is true that aging combined with a sedentary lifestyle causes a progressive loss of physical capacity that increases the risk of falls, and each fall generates more fear, which predisposes one to more frailty and more dependence in a self-reinforcing cycle. That is why fall prevention is crucial.
Sarcopenia (the progressive loss of muscle mass) is the biological mechanism that best predicts this trajectory. When muscles weaken, the basic activities of daily living can become an obstacle.
How can you avoid the loss of autonomy with age?
Functional dependence is not an inevitable consequence of aging. It is, to a large extent, the result of not maintaining muscle mass, mobility, and balance.
Progressive strength training is the intervention with the most evidence for preventing and reversing sarcopenia, even in people over 70. A program of several days a week with resistance exercises is enough to have a significant impact. In our active longevity guide, you can find guidelines on what exercises to do according to your age and starting point.
2. Dependence, loneliness, and being a burden
Here, two self-reinforcing fears mix: the fear of depending on others and the fear of being left alone.
According to the General Council of Psychology in Spain, one in two elderly people is at risk of unwanted loneliness. Certain factors often trigger it: the death of a spouse or close friends, retirement—which eliminates the work-based social network—or reduced mobility that limits social participation. Furthermore, the consequences are not just emotional. Loneliness is associated with a higher risk of cardiovascular disease, diabetes, cognitive decline, and premature mortality.
The fear of being a family burden also has a component of dignity: feeling that one’s own body puts one's children or partner in a difficult spot generates shame, guilt, and withdrawal. A study published in the journal Gerokomos shows that the greater the functional dependence, the higher the anxiety and depression, creating a loop that is difficult to break.
How can you avoid dependence and loneliness?
For functional dependence, the key is the same as we talked about before: maintain physical capacity before losing it. Maintaining a balanced diet, exercising, and controlling chronic diseases are documented strategies to reduce functional dependence in old age, which should be worked on as soon as possible (and not wait until problems appear). In our active longevity guide, we give you guidelines for all of this from age 30, 50, up to 100.
For loneliness, it is crucial to always keep in mind the importance of maintaining active social networks. Take care of friendships and ensure that social connection rituals do not depend on a single context (work, partner, a single activity...). After retirement, signing up for social activities like painting or book clubs can grow your network with people of similar tastes. For people who are starting to isolate themselves, cognitive-behavioral therapy for loneliness, mindfulness programs, and social groups are the interventions with the most scientific support.
3. Chronic disease and cognitive decline (including dementia)
Chronic disease is the most tangible fear and the one most linked to memories of our own parents. The general perception is that physical decline and diseases are an inevitable part of the aging process.
But the deepest fear of all is cognitive decline: losing one's memory, no longer recognizing loved ones, no longer being oneself. In Spain, more than 900,000 people suffer from dementia, with a prevalence of 27.7% in those over 85.
Since this is such a complex topic and we cannot generalize about every disease, we will look in more detail in the next section at some of the main ones (osteoarthritis, sciatica, incontinence, and Alzheimer’s or dementia). We will explain whether they are hereditary and to what degree they can be prevented or treated, all according to the latest scientific studies.
4. Image, stigma, and social discrimination
Ageism is a phenomenon so widespread that, according to the WHO, one in two people in the world holds ageist attitudes. The fear is not only external (being discriminated against) but also internal (internalizing the negative image of old age and applying it to oneself). Stereotypes about old age associate it with decline, unproductiveness, invisibility, and dependence. When that image is internalized, it generates what experts call self-ageism: the older person assumes that their limitations are normal, avoids seeking medical attention, stops demanding professional or social opportunities, and reduces their expectations for an active life.
Ageism has documented physical and clinical consequences: negative attitudes toward one's own aging increase mortality risk, impair functionality, worsen recovery after illness, and increase mental health problems. Age discrimination also leads to late diagnoses and suboptimal treatments when health personnel assume that certain symptoms are normal for one's age.
How can you avoid ageism?
Ageism is a cultural construct based on stereotypes. The image of old age as decline and dependence ignores the fact that older people are an enormously heterogeneous group, with very diverse capabilities, projects, and social contributions. That said, it can be complicated to change society’s attitude.
That is why we must work at a social level:
- With education and the dismantling of myths about aging. Follow us on Instagram where we publish content.
- Diverse and real visual representation of older people in media and brands.
- Intergenerational programs, as contact between generations is the most effective intervention for reducing negative stereotypes.
And at an individual level:
- Actively question the "I’m too old for this" narrative.
- Maintain active projects, learning, and roles.
- Understand that one's own perception of aging directly predicts physical and mental well-being: people with a positive image of aging live, on average, 7.5 years longer than those with a negative image.
What can be prevented? What science said in 2026
In 2026, there was a lot of talk about a study that reopened the debate on genetics and longevity. The idea that made it into many headlines was quite unsettling: genes might carry more weight than previously thought in life expectancy.
The problem, as often happens, is that the headline fell short.
Do genes determine how long you live?
Genes influence life span, but they do not determine it completely. Some studies have estimated significant genetic weight in life expectancy, while others give more importance to environment and lifestyle.
In a study from the Weizmann Institute published in Science in January 2026, researchers analyzed twin records from Denmark, Sweden, and the United States, concluding that approximately 55% of the variation in human lifespan is genetically heritable, double what was estimated until now. However, the study's own authors warn that this 55% figure is a statistical estimate based on a model: it does not mean your lifespan is set in advance, nor that habits are irrelevant.
But there is a distinction that we often lose in the conversation: living more years is not the same as living well.
Living more years is not the same as living well
As we have seen, what scares us is not getting older, but everything associated with aging. Life expectancy—that is, how many years a person lives—is one thing. Healthy life expectancy—that is, how many of those years are lived with autonomy, mobility, mental health, relationships, energy, and the ability to lead one's own life—is quite another.
Canadian doctor Peter Attia popularized these terms:
- Lifespan: total years of life
- Healthspan: years lived with good functional health
You may not be able to completely control how many years you will live, but you can certainly influence how you want to reach those years.
Often, our fear is not whether we will live as many years as our parents, but whether we will manage to live these last years with a better quality of life than they did.
Which of your parents' diseases can you actually inherit?
There are health complications that do have a family component, although this does not mean it will happen to you for sure. In most diseases associated with aging, we are talking about predisposition, not a death sentence. A predisposition would be like having a door that is easier to open, but whether or not it opens depends on many other factors.
Is osteoarthritis hereditary?
Osteoarthritis can have a hereditary component, but there is no single "osteoarthritis gene" that determines you will definitely develop it.
What can be inherited is a certain predisposition: the shape of some joints, the quality of the cartilage, the way the connective tissue responds to wear and tear, or a greater tendency to develop osteoarthritis in certain areas, such as the hands, hips, or knees.
But then other very important factors come into play, such as body weight, previous injuries, the type of work one does, a sedentary lifestyle, muscle strength, posture, diet, and inflammation maintained over time. That is why two siblings with a family history can age in very different ways. One may develop limiting joint pain at 60, while another may remain active for many more years if they have taken care of their weight, muscle mass, mobility, and the loads their joints support.
Even so, we want to make it clear that osteoarthritis cannot always be avoided, but it can be delayed, modulated, and managed better.

Are sciatica and herniated discs hereditary?
Sciatica is not a disease in itself, but rather a pain that appears when the sciatic nerve, or any of the nerve roots that form it, is irritated or compressed. It is usually felt as pain that radiates from the lumbar region down to the gluteus, the leg, or even the foot.
Some people have an inherited vulnerability in their spinal discs. For example, there may be differences in the composition of collagen, which is an essential protein that provides strength and structure to tissues such as discs, tendons, and ligaments. There may also be a family tendency toward disc degeneration, which is the progressive wear and tear of the discs that cushion the vertebrae.
But, once again, genetics does not act alone. Tobacco, excess weight, jobs involving repetitive lifting, spending long hours sitting, lack of strength in the abdomen and back, stress, and poor ergonomics can cause that predisposition to manifest sooner or with greater intensity.
Let’s think about our parents' generation. Many men performed hard physical labor for decades without a culture of prevention, physiotherapy, or compensatory strength training, and in many cases, they smoked. Many women carried heavy loads, took care of everyone, worked both inside and outside the home, and hardly had the time or social permission to take care of their own bodies.
You might also be interested in: on the Mr. Loris blog, you have a specific guide to understanding how to identify the cause of sciatica and an article explaining why sciatica returns and what you can do to prevent it.
We also offer solutions like the TENS Force electrostimulator, with a specific program for sciatica.
Is urinary incontinence inherited?
Urinary incontinence is not an inevitable consequence of aging. It is extremely important to repeat this, because for too long many women have heard phrases like "that's normal after childbirth" or "at your age, that's just how it is." Just because it's frequent doesn't mean it's inevitable (and just because it happens to you or is common doesn't mean you have to resign yourself to it).
There may be a certain family predisposition: some women have looser connective tissue or more vulnerable pelvic floor muscles. But the factors that most commonly trigger or aggravate incontinence are pregnancies, childbirth, menopause, smoking, chronic constipation, repetitive coughing, or high-impact sports.
But the pelvic floor can be trained. Although doing "Kegels" on your own is not always enough (many women don't know if they are contracting the muscles correctly). That is why, when symptoms occur, the ideal approach is to see a physiotherapist specialized in the pelvic floor.
As support in some cases, electrostimulation can help activate the musculature when voluntary training is not enough or when it is difficult to isolate the contraction. Furthermore, in cases where incontinence is present, urinary infections are often more common. That is why the urinary health and incontinence kit solution is ideal; it helps treat incontinence from home with TENS electrostimulation and helps prevent urinary infections with the cranberry supplement.

Are Alzheimer's and dementia inherited?
Few things are as distressing as having watched a mother, a father, or a grandparent lose their memory, orientation, or language.
In Alzheimer's disease, there are very specific familial cases, generally early-onset, in which there are determinant genetic mutations. But they are a minority. In the majority of cases, genetics increases or reduces vulnerability, but it does not decide the future on its own.
One of the best-known genes is APOE4. Having this variant may increase the risk, but it does not mean that the person will definitely develop Alzheimer's. And not having it does not guarantee absolute protection either.
The most important thing for practical life is that a significant part of the risk of dementia is related to modifiable factors. Among them are untreated hearing loss, hypertension, high cholesterol, diabetes, sedentary lifestyle, tobacco, depression, social isolation, poor sleep quality, obesity, alcohol, head trauma, and uncorrected vision loss.
Consider the importance of taking care of your hearing. Many older people isolate themselves because they hear poorly, participate less in conversations, become socially exhausted, and reduce stimuli without realizing it. Checking hearing and using hearing aids when indicated is not a minor detail.
Although better known, it is also crucial to keep the mind active. Reading, conversing, learning something new, doing memory exercises, writing, calculating, playing games, cooking by following recipes, leaving the house, and maintaining social bonds are everyday forms of cognitive stimulation.

In our cognitive health and memory collection, you will be able to find cognitive stimulation workbooks which, while not a vaccine against dementia, can certainly be part of a broader routine of mental activity.
Why your parents aged this way (and it wasn't just their genes' fault)
Sometimes we cannot help but look at our parents' aging as if it were a family prophecy. But many times, it was, above all, the result of an era. Our parents grew up and aged in a very different context. For decades, there was more smoking, less culture of prevention, less physiotherapy, less strength training, fewer check-ups, less awareness of sleep and nutrition, and less mental health. Furthermore, for years, chronic pain was treated late or poorly. The phrase "that's just part of getting older" has done a lot of damage because it turns treatable problems into resignation.
Epigenetics: how your habits work with your genes
Your habits can influence how certain genes are expressed. Your genes are like an instruction manual. You cannot change the book you inherited, but your body does not read every page in the same way all the time. Epigenetics studies those markers that help activate or silence certain genes without changing the DNA.
Exercise, sleep, nutrition, stress, tobacco, alcohol, inflammation, and the environment leave biological signals. Some can favor repair and balance processes; others can push toward inflammation, metabolic deterioration, or accelerated biological aging. This does not mean that you can magically "rejuvenate" or erase all diseases, but it does show that the body continues to respond even at 60, 70, and 80 years of age.
Is it too late if you are over 55?
No. It is not too late.
Naturally, the sooner you start, the better. But starting at 55 or 60 makes sense. In fact, many people notice very real changes when they incorporate strength training, walk more, sleep better, lose some weight if they need to, check their blood pressure, treat their hearing, or reduce alcohol.

It is not too late for your parents: what they can actually do now
Even if they have spent years accumulating unfavorable habits or ignored discomforts, the body still has room for improvement. At any age, even in advanced stages, processes of adaptation, recovery, and prevention can be activated.
Although it's not about changing everything all at once, here are some actions that, when incorporated little by little, can have a real impact.
- Incorporate adapted strength training. You don't need to lift very heavy; working the muscles improves autonomy, protects joints, and reduces the risk of falls.
- Sleep better. Reviewing schedules, routines, and possible problems like insomnia or apnea can make a big difference in energy, memory, and recovery.
- Walk more and move daily. Constant activity, even if it is moderate, has clear effects on cardiovascular and metabolic health.
- Medical check-ups up to date. Controlling blood pressure, glucose, hearing, vision, or bone health allows you to detect and treat problems before they limit your quality of life.
- Take care of nutrition (without extremes): Prioritizing fresh foods, sufficient protein, and good hydration helps maintain muscle mass, energy, and metabolic function.
- Address pain and limitations: Pain is not "normal for your age" if it is limiting: physiotherapy, therapeutic exercise, or appropriate treatment can greatly improve the situation.
- Reduce harmful habits. Reducing tobacco or alcohol, even late in life, still has measurable benefits.
- Take care of mental and social health. Maintaining bonds, projects, and cognitive stimulation is also part of aging better.
We explain all of this in more detail with specific tips in the guide to active longevity, which you can download for free.
