We all must have come across the phase: this is why women live longer than men. These are all over the social media, where men are performing more often than not, some experiments, without gears, just for fun, "in the name of science". The caption reads: this is why women live longer. However, is there really a science to it, other than the fact that women choose to do things more safely?

In the United States, women have a life expectancy of about 80, whereas men have 75. Women outlive men and this holds true regardless of the country women live, the money they make, and other factors. In fact, it is true for most other mammals too.

Dr Dena Dubal, a professor of neurology at the University of California, San Francisco told the New York Times, "It is a very robust phenomenon all over the world, totally conserved in sickness, during famines, during epidemics, even during the times of starvation."

But what are the reasons? These reasons are often more complicated and less established. It is important to note that only because women are outliving men does not mean they are living a better life. In fact, women tend to have shorter health spans, which means the number of healthy years in a person's life is less in women than men, confirmed Bérénice Benayoun, an associate professor at the U.S.C. Leonard Davis School of Gerontology.

As per a 2021 study titled, Sex differences in frailty: Comparisons between humans and preclinical models, found that women are more physically grail than men in old age. They are also more vulnerable, especially after menopause and are at more risk of developing cardiovascular issues and Alzheimer's disease because of age.

The key is in figuring out what makes one sex more resilient or vulnerable.

Genetics

For things which do not find easy explanations, scientists look for their answers in genes. Many research, including a 2020 study titled, The sex with the reduced sex chromosome dies earlier: a comparison across the tree of life, suggests that the XX set of female sex chromosomes may impact longevity. However, there has not been any clarity on how it affects longevity.

Another 2018 study titled, Female XX sex chromosomes increase survival and extend lifespan in aging mice, which was conducted by Dr Dubal's lab, looked at genetically manipulated mice with different combinations of sex chromosomes and reproductive organs. It was found that those with two X chromosomes and ovaries lived longest, followed by mice with two X chromosomes and testes. Mice with XY chromosomes had shorter life spans.

"There was something about the second X chromosome that was protecting the mice from dying earlier in life, even if they had testes. What if there was something on that second X chromosome that was in some ways a sprinkle of the fountain of youth," says Dr Dubal. While scientists have not yet looked at this factor in humans, Dr Dubal suggests that humans have the same hormones and sex chromosomes, and similar reproductive system that could corroborate the similar findings in people.

Hormones

Plenty research has shown that estrogen is responsible for longevity also effect on the immune system. The data also shows that before menopause, the female immune system tends to do better. In fact Dr Benayoun said that males tend to do much worse in response to infection.

Another 2017 study titled, Ages at Menarche and Menopause and Reproductive Lifespan As Predictors of Exceptional Longevity in Women: The Women's Health Initiative, found that women who experienced menopause later in life over the age 50 lived longer than those who experienced it earlier.

Lifestyle and Behavior

There are also disparity in behavioral patterns between men and women. This includes smoking, drinking heavily, which can contribute significantly to mortality. Women also have more "health promoting behavior", believe experts. Women are also more likely to socialize than men and thus it protects them from detrimental effects of social isolation and loneliness. In fact, a 2023 analysis published in Jama Network, titled, Widening Gender Gap in Life Expectancy in the US, 2010-2021, found that women are less likely to die by drug overdose or suicide.

Diabetes at 35 and diabetes at 60 are not the same. As we grow older, the way diabetes presents, the complications we worry about and even the way we treat it can change. This is why diabetes care after 60 needs to look beyond a single blood test.

HbA1c remains an important measure of average blood sugar over the previous few months. But for an older adult, it cannot be the only measure of good diabetes care.

Diabetes Symptoms Can Be Silent in Older Adults

One of the challenges with diabetes in older people is that symptoms may not always be obvious. A person may not experience the typical excessive thirst, frequent urination or unexplained weight loss, even when blood sugar levels are high.

At the same time, older adults can be more vulnerable to diabetes-related complications affecting the eyes, kidneys, nerves, heart and blood vessels. Vision problems are particularly important because loss of vision can directly affect mobility, confidence and independence.

This makes regular screening essential, even when a person feels completely well.

The Same HbA1c Target Does Not Suit Everyone

There is no single HbA1c cut-off that is appropriate for every older adult. Treatment goals need to consider age, overall health, cognitive function, physical function, existing complications and the person's ability to manage treatment independently. Current diabetes standards specifically recommend individualising glycaemic goals in older adults.

For example, a healthy 65-year-old who is active and independent may have very different treatment goals from an 80-year-old who is frail, has multiple medical conditions or needs help with daily activities.

The goal should be good blood sugar control without causing unnecessary harm, particularly hypoglycaemia.

Treatment After 60 May Need to Be Different

As people age, kidney function can change, meals may become irregular and multiple medicines may be prescribed for different conditions. These factors can increase the risk of low blood sugar and make complex treatment plans harder to follow.

Therefore, doctors may need to review medicines regularly and simplify treatment when appropriate. The focus should be on finding a treatment plan that is effective, safe and practical for that individual.

Look Beyond Blood Sugar

A comprehensive diabetes review in an older adult should also consider:

• Eye and retinal health
• Kidney function
• Blood pressure and cholesterol
• Foot and nerve health
• Risk of hypoglycaemia
• Nutrition and unintended weight loss
• Muscle strength and mobility
• Memory and cognitive function
• Risk of falls
• Ability to take medicines and manage diabetes independently

The aim is not simply to produce a better HbA1c report. It is to prevent complications while helping the person remain active and independent.

Nutrition and Exercise Should Protect Independence

Older adults with diabetes need adequate nutrition, particularly protein and other nutrients needed to maintain muscle mass. Excessive dietary restriction can sometimes do more harm than good.

Physical activity is equally important. Walking, strength exercises and balance activities, when medically appropriate, can help maintain mobility and reduce the risk of losing independence.

Growing Older Well With Diabetes

Diabetes management after 60 should be personalised and regularly reassessed. What is appropriate at 60 may not be appropriate at 75 or 85.

As we mark the International Day of Older Persons, the message is simple: living well with diabetes in later life is about much more than achieving a particular HbA1c.

We need to treat the person, not just the number — protecting their health, safety, dignity and independence as they grow older.

Changes in voice pitch, volume or clarity in older adults could be an early warning sign of cognitive decline, according to a new analysis.

The study, published in the Journal of Voice, found that older adults who experienced a decline in voice quality had a higher risk of cognitive impairment or dementia than those without a voice disorder.

Voice Disorders And Higher Dementia Risk

The study tracked the health of more than 833,000 older Americans. Researchers found that people with a voice disorder had a 58% higher risk of cognitive impairment or dementia than those without voice problems.

The risk was even higher among people who had both a voice disorder and hearing loss, a well-recognized risk factor for Alzheimer’s disease.

A brief episode of hoarseness does not mean that a person is developing dementia.

However, persistent or noticeable changes in the voice, particularly when accompanied by hearing loss, may warrant a medical evaluation and, where appropriate, an assessment of cognitive health.

“We found the strongest link with dementia among patients experiencing a voice disorder and hearing loss,” said study author Dr. Robert Sataloff, a professor and chair at Drexel University’s College of Medicine.

“Importantly, we found that those with a voice disorder and no hearing loss were at greater risk than patients who experience hearing loss only. It may be valuable for many of these patients to talk with an otolaryngologist who can arrange a cognitive assessment to help patients develop an appropriate care plan.”

Why Voice Changes Can Signal Cognitive Decline?

The researchers speculate that voice disorders may contribute to cognitive decline by limiting social interaction, which can also be affected by hearing loss.

People who have difficulty speaking or hearing may avoid social gatherings or group activities because they feel embarrassed or uncomfortable about their limitations. However, social engagement can help keep the ageing brain active by providing ongoing mental stimulation.

“If you have a voice disorder that impacts how your voice sounds or if it’s painful when you attempt to talk or sing, it’s only natural to participate less often in brain-supporting social or other engaging activities,” Dr. Sataloff said.

Speaking less may mean less social and cognitive stimulation, which could potentially contribute to dementia risk. However, the researchers also noted another possibility: changes in the brain associated with dementia could themselves contribute to voice problems. However, this has not been directly studied.

Voice Problems Can Have Treatable Causes

Most people with voice disorders will not go on to develop Alzheimer’s disease. Voice changes can have several other causes, including thyroid problems and cysts on the vocal cords, some of which can be treated effectively.

Speech therapists can also help people with impaired speech communicate more effectively and confidently.

Seeking medical attention for persistent voice changes can therefore help identify treatable causes and determine whether further evaluation, including a cognitive assessment, is needed.

As the 2026-27 flu season begins in the US, doctors are reminding people that influenza can cause more than just cough, fever and a runny nose. Symptoms can come on suddenly and affect the entire body, with some patients also developing gastrointestinal symptoms.

During the 2025-2026 flu season, influenza caused at least 32 million illnesses, 390,000 hospitalizations and 24,000 deaths in the US, according to preliminary data from the Centers for Disease Control and Prevention (CDC).

According to the World Health Organization, from February through August 2026, influenza A(H1N1)pdm09, A(H3N2) and influenza B viruses circulated across regions. Influenza A viruses predominated in most regions, while influenza B dominated in Northern and Western Africa, North America and Eastern Asia.

While it is too early to know what the season ahead will look like, knowing the range of flu symptoms can help people recognize the infection. These include the classic symptoms of sudden fever, chills, body aches and extreme fatigue, as well as vomiting and diarrhea in some children.

Influenza commonly affects the nose, throat and lungs, but its symptoms can be widespread.

The most common symptoms include:

• Fever

• Chills

• Body aches

• Extreme fatigue

• Headache

• Sore throat

• Runny or stuffy nose

• Cough

Family physician Carlos Galindo at Texas Health Family Care said fever, chills and body aches are the classic flu combination. People may also develop a sore throat, runny nose and headache, according to the American Medical Association.

Unlike the gradual tiredness that can accompany a cold, flu-related fatigue can be intense.

Galindo described it as significant lethargy and malaise, with some patients feeling completely drained.

Watch For Severe Body Aches And Fatigue

One of the key features doctors want people to recognize is how quickly influenza can make someone feel unwell.

Family physician Christopher Zipp of Atlantic Health in Morristown, New Jersey, said flu symptoms can develop over just a few hours, with fever, chills and body aches appearing suddenly.

However, flu symptoms can overlap with those of other respiratory infections, so symptoms alone cannot always confirm that someone has influenza.

Children Can Have Vomiting And Diarrhea

Flu symptoms can also differ between children and adults. While fever, chills, body aches and respiratory symptoms are common, children may also develop gastrointestinal symptoms such as vomiting and diarrhea.

These symptoms can occur alongside cough, sore throat or other signs of respiratory infection.

When Can Flu Become Serious?

For most people, influenza is an unpleasant but temporary illness. However, it can sometimes lead to complications such as pneumonia and hospitalization, particularly in people with underlying health conditions.

Symptoms that become severe or worsen rather than improve warrant medical attention, especially among people at higher risk of complications.

In the US, many flu cases are seen between January and March, although influenza can circulate outside the peak season as well.

Doctors generally recommend flu vaccination around September or October to build protection before activity increases. It takes about two weeks for the body to develop protection after vaccination. Flu vaccination has been shown to reduce flu-related doctor visits by about 40% to 60%.
