Bone Health In Older Adults (Credit-Canva)
Strengthening your bones is not something that can happen overnight, it takes years for your body to build strong bones and even then, it is natural for them to lose their dexterity. All you can do is keep your body healthy to make sure it is prepared for any unexpected situations. For years, many older adults have been told to take vitamin D and calcium supplements to keep their bones strong and prevent falls. However, a new report from U.S. Preventive Services Task Force (USPSTF) is changing that advice. This report suggests that for most older people, these supplements don't actually prevent falls or broken bones. This might be surprising news, we must understand why falls happen more often as we age, what vitamin D and calcium do in the body, and most importantly, what you can do to stay safe and prevent fractures.
According to the report, vitamin D supplements don't seem to help prevent falls or broken bones for most people over 60. They also found that these supplements, especially with calcium, might increase the risk of kidney stones. This report doesn't mean people with weak bones (osteoporosis), low vitamin D, or who take vitamin D for other health reasons shouldn't take it. It just means that for most healthy older people, these supplements don't prevent falls and fractures.
There are many reasons why older people are more prone to breaking their bones. Our bones are strongest when we're in our 20s and 30s, and they get weaker as we age so naturally, they can break easily. It can also be harder to move around as we get older, sometimes because of problems like arthritis this can affect how we walk and make us less steady.
There are also different issues like neuropathy, which is a nerve problem that can also make it harder to feel your feet and keep your balance. Eyesight is also a culprit as it can cause you to feel dizzy and fall. Some medicines can also make people feel unsteady, and older people often take more medicines than younger people. Low vitamin D itself can also increase the risk of falls, so keeping vitamin D levels up is still important.
USPSTF recommends a few better ways to protect your bone health and prevent broken bones and falls.
Regular walks strengthen your muscles and bones, which helps you stay steady on your feet. It is as simple as practice makes perfect so the more you walk, the better it is. Walking also improves your balance, making you less likely to fall.
Strength training, like lifting weights or using resistance bands, makes your bones stronger and helps prevent fractures if you do fall. It is like a safety cushion, but you must be careful while doing so because it can lead to injuries if done too much.
Activities like tai chi, Pilates, and yoga can improve your balance and coordination, making you more stable and less prone to falls. These can also help you improve your muscle flexibility and strength that in turn helps your body be stronger.
If you have osteoporosis, talk to your doctor about medications that can help strengthen your bones and lower your risk of fractures. Many medications can also have unsavory side effects like weakened joints, losing muscle strength, etc.
A proper diet goes a long way when it comes to your entire body health. So to keep up with your body’s nutrition and muscle health, eat more protein along with a balanced meal that includes loads of fiber, healthy fats and carbs.
Having poor eyesight can be difficult, not only does it make life difficult without glasses, but it also increases the possibilities of getting into minor accidents like bumping into people and missing objects placed in front of us.
Getting enough sleep is also important because when you are not sleeping, you get disoriented and can ignore even obvious things like the last stair in the staircase. Make sure you get enough sleep to keep you fresh and focused.
There are many things that can cause you to have accidents, even in your home. To avoid such falls, make sure there are no lose ends like crooked floor panels, rugs that are sticking out or protruding furniture that can hurt your knees

Metformin Brain: A popular diabetes drug, prescribed to manage type 2 diabetes by controlling blood sugar, which has been in use for 60 years - metformin, now shows how it is directly linked to the brain.
A drug used for over six decades did not have a study that made scientists sure of exactly how it works, until now. Researchers from the Baylor College of Medicine in the US were able to identify in 2025 a brain pathway that the drug seems to work through. It also has impacts on biological processes in other areas of the body.
"It's been widely accepted that metformin lowers blood glucose primarily by reducing glucose output in the liver. Other studies have found that it acts through the gut," said Makoto Fukuda, a pathophysiologist at Baylor.
"It's been widely accepted that metformin lowers blood glucose primarily by reducing glucose output in the liver. Other studies have found that it acts through the gut," said Makoto Fukuda, a pathophysiologist at Baylor.
In a 2025 study on mice, researchers observed that metformin travels to the VMH and switches off Rap1 activity. This action appears to be crucial for its ability to control blood sugar. To test this further, scientists bred mice that lacked Rap1. In these mice, metformin no longer improved diabetes-like symptoms, even though other medications still worked.
This points to something important. Metformin may be working through a completely different pathway compared to other diabetes drugs, one that depends on the brain.

The researchers also identified specific nerve cells involved in this process. They found that SF1 neurons become active when metformin enters the brain, suggesting these cells play a direct role in how the drug works.
These findings could change how doctors and scientists think about diabetes treatment. If metformin’s brain pathway is confirmed in humans, future therapies could be designed to target these exact neurons, making treatments more precise and possibly more effective.
There is also a bigger picture. Metformin has already been linked to benefits beyond diabetes, including slowing aspects of brain aging and improving longevity. In one study involving postmenopausal women, those taking metformin had a significantly lower risk of dying before the age of 90 compared to those on another diabetes drug.

While the results are promising, human studies are still needed. If confirmed, this discovery could open the door to new treatments that not only manage blood sugar better but also tap into the brain’s role in overall health and aging.
It also reinforces an emerging idea that metformin is not just acting on the body’s metabolic organs, but quietly influencing the brain at much lower doses.

Metformin is a safe and effective drug used by type 2 patients for the last six decades to control their blood sugar levels and improve the way the body handles insulin.
A recent study showed that metformin can also be crucial in reducing the risk of vision loss in people over the age of 50, known as age-related macular degeneration (AMD).
The observational study, published in the BMJ Open Ophthalmology, showed that metformin can cut down the cases of AMD by nearly 40 percent in people with Type 2 diabetes over five years.
“We have found a significant association between metformin use and a reduction in the incidence of intermediate AMD by 37 percent in people with diabetes over 5 years. Previous epidemiological studies of metformin and AMD have used secondary data on AMD,” said corresponding author Nicholas A. V. Beare, from the University of Liverpool, UK.
“Given metformin’s anti-aging therapeutic effects, the reduction in risk is plausible and warrants prospective clinical trials,” he added.

While currently there is no specific treatment option for AMD — a common cause of blindness in high-income countries — scientists have shown interest in metformin as a candidate drug for treating AMD and reducing its progression.
It is because of metformin's antioxidant, anti-inflammatory, antiangiogenic, and antifibrotic effects. Metformin is also postulated to delay ageing and ageing-related diseases.
Previous research has also identified metformin as a potential treatment for all stages of AMD. Researchers also noted that the common diabetes drug is readily accessible and has a strong safety profile.
The BMJ study analyzed more than 2,500 participants aged 50 or above who attended retinopathy screening in 2011.
All participants had Type 2 diabetes and gradable fundus photographs — high-quality retinal images.
Individuals prescribed oral metformin had a 37 percent lower risk of intermediate AMD by five years. The results are consistent with known biological mechanisms, given metformin’s potential favourable effects on AMD progression, researchers reported, the researchers said.
The team, however, acknowledged limitations such as a lack of proper data regarding the dose, duration of prior use, or compliance with metformin use.
Further, there were only a relatively small number of participants developing advanced AMD – an inevitability in population-based studies. They urged for a clinical trail to prove metformin's potential in treating AMD.

Age-related macular degeneration (AMD) is a disease of the retina. It happens when a part of the retina called the macula is damaged. It results in the loss of sharp, straight-ahead vision.
The condition commonly affects adults over 50, and causes
While AMD rarely causes total blindness but affects central vision, making reading and driving difficult. It is of two types:

Harry Potter star Daniel Radcliffe has quit smoking after 20 long years. The reason: his two–year–old son with girlfriend Erin Darke.
Speaking to media outlet Vulture, the 36-year-old English actor shared that after becoming a father, he was inspired by intrusive thoughts about his mortality, which enabled him to quit the deadly habit after two decades.
"I smoked for 20 years pretty heavily, and I was never even thinking about quitting, and then shortly after having my son, the intrusive thoughts of my own death really helped as an incentive to quit," Radcliffe was quoted as saying.
Radcliffe also shared how a book -- The Easy Way to Quit Smoking, by Alan Carr -- helped him decide to quit smoking.
"It may not work for everybody, but it really worked for me," noted the star, currently starring in the Broadway play Every Brilliant Thing.
Earlier this month, the actor spoke with WSJ Magazine and shared that from being on “cigarettes all day”, he's transformed into a fitness freak.
Smoking can affect all organs in our body. While lung cancer and tuberculosis are the most prominent ones, smoking can seriously increase the risk of several chronic diseases. These include:
While quitting tobacco is important, it is a difficult task, with some people finding it harder to quit than others. It may be important to seek help quitting.

These strategies have shown varying levels of success in aiding smokers to quit permanently. In addition, alternative methods like e-cigarettes and mindfulness-based techniques have gained traction in helping reduce smoking addiction.
Behavioral Support
Quitting smoking isn’t just about resisting cravings. Often, behavioral support through counseling or therapy is crucial for tackling the psychological aspects of addiction. Behavioral therapy involves working with a trained professional to identify triggers, develop coping strategies, and create a tailored quit plan. Research shows that combining counseling with other quit methods can significantly increase success rates.
Prescription Medications
Some medications, such as varenicline (Chantix) and bupropion (Zyban), have been shown to help people quit smoking by reducing cravings and withdrawal symptoms. Experts suggest that varenicline works by blocking the effects of nicotine in the brain, while bupropion is an antidepressant that helps manage withdrawal symptoms. Both medications are generally more effective when combined with behavioral therapy.
Nicotine Replacement Therapy (NRT)
Nicotine replacement products, such as nicotine patches, gums, lozenges, and nasal sprays, deliver controlled amounts of nicotine to ease withdrawal symptoms. According to experts at Harvard Health, NRT can double the chances of quitting by alleviating physical cravings while the person works on overcoming the psychological addiction.
