Physiology of Old Age

When it comes to aging, certain questions may arise, such as: Why do our bodies age, and how old can people get? But growing older is about more than just how many years you have lived.

Our bodies are complex organisms with countless features and functions. It is normal for damage or mistakes to occur in our cells and tissue over time. These changes aren't a problem in our younger years: Our bodies can simply repair many of them, or have enough reserves to make up for them. But the ability to deal with this damage decreases as we grow older. So, it starts adding up, leading to signs of aging.

In few countries, people between the ages of 60 and 75 are considered to be “of older age” or “elderly,” those between 75 and 90 are often described as “old,” and those between 90 and 100 are referred to as “very old.” People who are over 100 are called centenarians.

But the number of years you have lived is just one way to determine your age – which is then known as your chronological age. People of the same chronological age often haven't aged to the same extent, though. This can be explained by “biological age,” which is based on how healthy you are overall, as well as your physical and mental fitness.

Humans probably have a maximum lifespan of just over 120 years. But it is extremely rare for people to reach such an old age. The average life expectancy is currently about 78 years for newborn boys and about 83 years for newborn girls. Statistically speaking, your life expectancy is a bit higher if you have already reached a certain age: For instance, a 60-year-old can expect to live to about 82 if they're a man, and to about 85 if they’re a woman. It's not clear why women tend to live longer than men.

It is thought that the age you reach is partly determined by the genes you have inherited – by the DNA in your cells. Some people may only start becoming frail later, and live longer, as a result. But other factors have a positive impact too. These include living a healthy lifestyle with a lot of exercise and a balanced diet, being emotionally stable and having an intact social network.

What happens to your body when you age?

Your body is made up of various types of tissue. Some consist of cells that don't live long so they constantly have to be replaced – such as skin cells. Over the years, these cells are replaced at a slower pace because fewer skin cells can divide. In other organs, the cells don't ever divide. One example is nerve cells in the brain. Although these cells live for a long time, they may eventually die and aren’t replaced.

If cells aren’t renewed or if they die, the affected organs can no longer function as well as they did before. Many organs also lose mass (get smaller or “thin out”) over the years. But because our organs have large reserves in order to cope with greater strain, when necessary, this shrinking of reserves isn't noticeable for a long time. The typical signs of aging only appear once the reserves have become a lot smaller. These signs of aging aren't medical problems, though, and it’s often possible to counteract them for a long time: For example, if muscles start becoming weaker, you can do exercises to strengthen them. Sports and exercise are considered to be good for you anyway, for instance to keep your cardiovascular system (heart and blood vessels) fit and other organs healthy.

Aging

Some signs of aging can be seen from the outside: Your hair turns grey, and wrinkles and age spots appear on your skin. Our bodies are less able to store fluid in older age, so our spinal discs shrink and lose elasticity, for instance. As a result, people get smaller as they grow older.

When these kinds of changes happen in organs and tissues inside the body, they usually aren't noticeable for a long time. In some people, they only become apparent under strain or in very old age. In others, this happens sooner.

As we grow older, it takes longer for signals to travel along our nerves, and our brains can't process information as well as they used to. This makes it harder to remember new things and react quickly. Our sensory organs gradually decline too: for instance, it's typical to develop age-related farsightedness in your mid-forties and hearing problems in older age. Your ability to smell and taste things can get worse over time, too.

Growing older

Growing older means having a wide range of experiences and going through changes, both mentally and physically. Throughout life, our body and mind adapt to external factors and events, including aging itself. This can happen subtly and subconsciously over a long period, for instance, in the course of your working life or family life. Or it might happen more obviously and on purpose, for instance, when training for a sporting goal or during rehabilitation after a serious illness.

People continue to change for as long as they live. Growing very old can be accompanied by loss and limitations, and the challenge of having to adapt to new circumstances again and again. But the aging process usually happens so slowly that this adaptation is constant and gradual. Because your family and friends grow older with you, you experience many of the changes together. When things start becoming more difficult, remaining physically active and drawing on your life experience and wisdom can help you deal with a lot of the challenges you face.

Contentment and happiness are just as valuable in older age as they are in the earlier years of life. A lot of elderly people enjoy their retirement, free of many previous expectations and constraints. Some look for new tasks, while others are happy to have more time for themselves, their loved ones, and friends. The important thing is to stay active for as long as possible, both mentally and physically

What's normal at your 60s, 70s, and 80s.

It's no secret your mind and body change as you age. The process starts somewhere in your 30s. Cells begin to die off. Organs work a little less well. This raises your risk for certain diseases and disorders.

But these changes aren't the same for everyone. Genes, lifestyle, and environment all play a role in how you'll feel during your twilight years. And adopting healthy habits early can help you avoid some of these pitfalls.

Brain and Cognition —

How you think, learn, and remember changes throughout life.

The part of your brain in charge of storing vocabulary and general knowledge tends to stay the same or gets stronger with age. And your abstract reasoning skills — the ability to think about complex ideas — stay pretty sharp in most older adults.

But your brain starts to get smaller in your 30s and 40s. That shrinkage speeds up around age 60. On top of less mass, older brains tend to get less blood flow.

These age-related changes could have some unwanted side effects.

Once you hit 70, your attention span might get a little shorter, and some things might be harder to recall. You might search for words, something scientists dub the "tip-of-the-tongue" state. And it can be harder to learn new information, such as a foreign language.

But your brain can adjust to some things. For instance, you might lose nerve cells in one area and grow more in another. Connections in other areas may strengthen. Some experts think this is the key to what we call wisdom.

Some people make it to 90 without serious cognitive decline. On the other hand, about one-third of people 85 or older might get Alzheimer's disease or another form of dementia.

It's common to have occasional memory slips as you age. But there's a big difference between misplacing your keys and forgetting what year it is.

A healthy heart can work well at any age. But the shape, strength, and electrical signals of your heart and blood vessels do change over time.

Blood vessels get thicker and stiffer with age. That makes it harder to push blood through your body. Your blood pressure might go up or not stabilize as quickly. You might get dizzy when you stand up.

The aging process doesn't cause heart and blood vessel problems for everyone. High blood pressure is the most common heart condition for people 75 and older. Heart disease is the leading cause of death for both men and women.

An aging immune system is slower and less powerful than a younger one. So, you're more vulnerable to inflammatory diseases, infections, cancer, and other things as you age. For this reason, vaccines don't work as well in most people 65 and older. Scientists have a name for these age-related changes: immunosenescence and inflamm-aging.

While our overall defences decline with age, there's some evidence that our immune system adapts in a way that might help us live longer. For instance, you store more memory T cells as you get older. Those are white blood cells that can recognize and attack viruses or bacteria that made you sick in the past.

But aging adults tend to have fewer naive T cells. That's the part of your immune system that learns to fight off new germs, like the coronavirus that causes COVID-19.

Here's how the five senses are impacted by aging:

Parts of your eye get stiffer, denser, yellower, and drier as you get older. In their 40s, almost everyone starts to get blurry close-up vision. By your 60s, you may not see as well in low light, and colours may look less vivid.

Magnifying glasses and other vision aids can help you see better. You may have sudden changes or you may lose part or all of your eyesight. Some people have eye issues that go beyond age-related decline.

Long-term noise exposure can hurt your hearing. But about half of all people older than 75 have age-related hearing loss, or presbycusis. It happens gradually and usually affects both ears equally.

These two senses go hand in hand. And in your 50s, you might notice that some flavours change, especially sweet and salty ones. Some foods might taste bitter or bland. That's partly because your taste buds generally get less sensitive with age, and nerve endings in your nose die off, and the lining becomes thinner and drier.

Older skin has fewer nerve endings. You may be less sensitive to pain, temperature, or pressure. That might raise your odds of certain kinds of injuries, such as burns.

But tell your doctor if you have numbness. Some health conditions can damage your sense of touch beyond age-related changes. Some examples include diabetes, Parkinson's disease, mini-strokes, and arthritis.

Your gums might pull back as you get older.

Tooth enamel can wear down, and teeth can become less sensitive. Your mouth can get a little drier. Common medications can sap your saliva even more.

These age-related changes can leave your mouth vulnerable to bacteria and decay. That ups your odds of tooth loss and cavities.

But there are steps you can take to keep your mouth and teeth healthy at any age.

 

Keys To a Healthy Brain and Body

Stay Active

If there were a magic bullet for aging, this would be it. Regular physical activity can boost blood flow and help you form new cells and connections in your brain. It can improve your sleep and mood, ease inflammation, and ward off a lot of other health conditions. Dance, garden, go for a walk, or hit the gym – whatever gets you moving at least 150 minutes a week.

 

Older bodies also make less collagen and elastin, and you lose fat in certain areas. As a result, your skin tends to sag, wrinkle, and thin. Bruises and scratches may take longer to heal. You also sweat less as you age. You might not be able to cool yourself off quickly if you get hot.

Long-term sun exposure can lead to more wrinkles and dark spots. The sun's rays can also make your skin looser. Melanin gives skin its colour, offers some protection from certain kinds of sun-related aging.

Your bones break down and rebuild daily. But once you hit middle age, the breakdown happens faster than the rebuild.

Bone weakness is more common in everyone older than 50. But your odds of low bone mass are higher if you're female. That's partly due to a post-menopausal drop in oestrogen, a hormone that supports bone density. Female bones are also smaller and less dense than male bones.

It doesn't happen to everyone, but older people are more likely to get osteopenia. Your doctor might call that low bone mass. It can be an early warning sign of osteoporosis. That's a condition where your bones are very weak and can break easily.

It's natural to lose about 10% to 15% of your muscle mass and strength over your lifetime.

 

Severe muscle loss, or sarcopenia, isn't a natural part of aging. It's often the result of a lack of physical activity or another health problem. The condition affects as many as 13% of people ages 60 to 70. That number goes up to 50% for the 80 and older crowd.

The good news is you can avoid or delay a lot of age-related muscle loss. The key is regular resistance, or strength, training. That's exercise that targets your muscles. If you maintain your strength, you're more likely to live independently, fall less, and recover from serious injuries faster.

Resistance training – exercise can be safe for all older adults.

Aim to work out all your major muscle groups 2 to 3 times a week.

Along with regular physical activity and a healthy diet, resistance training may lower unhealthy fat around your belly and internal organs. By the time you turn 75, you may have about twice the amount of body fat you had in your younger years. Too much of it, especially in your midsection, can raise your risk for health problems like diabetes.

It's natural for your metabolism to slow around age 60.

At the same time, you might not be as hungry as you used to be, especially if you can't taste your food very well. Around 20% to 30% of older adults don't eat enough calories.

Older stomachs also lose some of their stretchiness and empty more slowly. You might feel fuller faster. Muscles in your lower throat might weaken, and the flap that keeps food in your stomach might pop open more often. Around 1 in 4 people older than 75 take heartburn medication.

Compared to when you were younger, your blood sugar might spike more after a meal. That's not a big deal for everyone, but unmanaged high blood sugar can lead to diabetes.

Food might move through your intestines a little slower. That doesn't cause problems for everyone, but up to half of older adults complain of constipation. You also lose certain digestive enzymes as you age, including the one that helps you process dairy.

It's also harder for the aging gut to absorb some nutrients from food.

 

Reproduction and sex.

The aging process can affect them in the following ways:

Vagina - Post-menopause, lower oestrogen levels can sap some of the moisture from your vagina. The tissue can also get thinner and less elastic. For some people, this can cause itching, burning, or pain during sex.

For most women, aging and menopause don't affect sexual satisfaction. But discomfort can. Long-lasting vaginal moisturizers and other lubricants might help.

Penis.

It's natural for blood flow to go down. You should still be able to have an orgasm and get an erection, but tell your doctor if you can't. Some older men get erectile dysfunction. That's not a natural part of aging. You might need medication or treatment for a health problem that affects your blood vessels.

 

Kidneys

 

For most people, they get smaller and less efficient. Healthy, older kidneys can work well. But there's not much wiggle room for damage. If you're older than 60, check with your doctor about a kidney disease screening. You might not notice symptoms early on.

 

Bladder.

Your bladder muscles can harden and get less stretchy. Your bladder wall and pelvic floor muscles can weaken. You might not be able to empty your bladder very well. That can raise your odds of urinary tract infections.

Some nerve or muscle problems go beyond the aging process. You could have another health condition, such as diabetes or Parkinson's disease. And health issues such as arthritis can make it hard to get to the toilet quickly.

 

Prostate - Certain blood markers for prostate health go up with age. Your prostate can also swell as you get older. That might slow or stop pee from leaving your bladder. Or you might pee more often, with less force, and take longer to get started.

 

Urethra.

This is the tube where your pee comes out. If you're female, it gets shorter and thinner. It might not be able to close all the way. Pee might come out when you don't want it to, like when you cough or sneeze. That's called stress incontinence. Bladder control problems can make this issue worse.

What are the Problems Faced by the Elderly

Process of Aging

Late adulthood challenges can be quite cumbersome, whether related to health or general societal issues. But what can be the biggest challenge to older adults? What are the problems faced by the elderly in our society? In this post, we will review elderly problems and solutions.

What Are the Major Challenges Facing the Elderly?

Problems of the elderly can be attributed to a number of factors. Everyday problems for the elderly include physical health, mental health, ageism, and financial insecurity. Below, we will take a look at problems faced by senior citizens and solutions.

Physical Health Problems of the Elderly

The biggest challenge to older adults can often be their health. To monitor these old-age problems, it’s best to get regular checkups and monitor your body for changes. Depending on the health concern, possible solutions to these problems can include a healthy diet, exercise, and/or medications. Some of these health concerns include:

• Heart disease
• Diabetes
• Hearing loss
• Cataracts
• Chronic obstructive pulmonary disease
• Heart attack and/or stroke
• Extra susceptibility to sexually transmitted diseases
• Muscle weakness
• Fatigue
• Loss of balance, which can result in falls
• Malnutrition
• Oral health issues, such as dry mouth and gum disease
• Incontinence and constipation

However, elderly issues are not limited to just physical health. Maintaining mental health should also be a top priority for elderly individuals. In the next section, we’ll review some possible mental health problems of older people.

Mental Health Problems of the Elderly

According to the World Health Organization, approximately 15% of adults aged 60 and over suffer from a mental disorder. Furthermore, life changes such as retirement or bereavement could also impact an elderly individual’s mental health. Speaking to a mental health professional for diagnosis and treatment can help alleviate some of these symptoms, as well as calling 988 for support. Some examples of mental health problems older adults experience include:

 Cognitive decline, including Alzheimer' s and dementia

• Depression

• Anxiety

• Sleep disorders

• Substance abuse

• Personality disorders, which can increase in symptoms as one ages

Older adults' problems are not limited to health issues; they can also face challenges from external societal factors. In the next two sections, we will review some of the additional problems the elderly encounter.

** Ageism Problems of the Elderly

** ageism can lead to feelings of loneliness and isolation among older individuals, both of which can manifest as physical health symptoms. The best way to combat ageism is to speak up as needed and not allow internalized shame about your age to limit your accomplishments. Types of ageism can range from general disrespect to systemic inequalities, which include:

• Interpersonal ageism: This occurs when supervisors refuse to assign tasks based on your age, or family members make subtle jabs.

• Self- directed ageism: This is when you internalize negative perceptions about your age.

• Institutional ageism: Social norms can often result in unfair treatment for older adults. For example, the medical field typically does not provide adequate representation for older adults in research and clinical trials.

Lastly, we will review the financial problems faced by older people.

** financial Problems of the Elderly

** the National Council on Aging (NCOA) compiled a list of financial challenges that the elderly encounter. Some of these include:

• Roughly 1 in 3 older adults over age 65 are economically insecure, with incomes below 200% of the Federal Poverty Level (FPL).

• On average, the 2. 3 million older adults on Supplemental Security Income (SSI) receive just $511 each month.

• 61% of households headed by those 65 or older had debt in 2016, with the median debt of senior- led households being $ 31, 31,050.

• In 2020, 5. 5.2 million older Americans faced the threat of hunger, with Black, Hispanic, Native American, lower- income, and disabled populations being the most likely to experience hunger in the United States.

The NCOA has several programs and products to help elderly people with financial issues. These include:

Center for Benefits Access. This helps community-based organizations find and enrol seniors in benefits programs.

Senior Community Service Employment Program (SCSEP). Via a grant from the U.S. Department of Labour, SCSEP helps adults over age 55 return to or remain active in the workforce through training and job searches.

Age Well Planner. Answer a few questions and get personalised information to address financial and health needs.

Benefits Check Up®. This program connects older adults with benefits programs that can help pay for health care, food, utilities, and other needs.
