Our brain is just like a muscle and it thrives on exercise. Moreover, it is the fastest-aging organ in the body. Studies show that brain volume naturally decreases with age due to neuronal loss, starting as early as your late 20s or 30s. This process accelerates over time, leading to a decline in cognitive functions such as memory, processing speed, and decision-making.
However, there is a way to counter it. Neurologists across the world agree that frequently playing brain games can prevent brain ageing. Backing them up is research showing that brain-training games may help improve attention levels, memory, response time, logic skills, and other measures of cognitive function if played over a long period.
And the good news is that these brain games are affordable and easily accessible to all. you just need a pen and paper for sudoku and the same goes on for crosswords. However, if you are someone who is up for a high-tech, options for brain games are plentiful.
To give your brain a workout while having fun, try these games and activities:

Non-healing mouth sores are often brushed off as minor issues, but when they persist for more than two weeks, they can signal something more serious.
Mouth ulcers are common and are often caused by stress, minor injuries, or nutritional deficiencies. Sores that do not heal may indicate underlying health concerns, particularly oral cancer.
"Early-stage oral cancers can present as painless ulcers or patches inside the mouth, making them easy to overlook. Conditions like Oral Cancer, Leukoplakia, or Lichen Planus may initially appear as harmless lesions but can progress if left unchecked," Dr. Mandeep Singh Malhotra, Director – Surgical Oncology at the CK Birla Hospital, Delhi, told HealthandMe.
Dr. Tejinder Kataria, Chairperson - Radiation Oncology, Medanta Hospital, Gurugram, added that mouth sores that don't go away after two to three weeks could be an early sign of oral cancer.
"These sores can be red or white and hurt or bleed easily. This is not the same as regular ulcers," he told HealthandMe.
The experts noted that non-healing sores can also be associated with systemic conditions such as

Oral cancer is a wide term for cancer that affects the inside of your mouth, and it typically presents itself as white patches or sores that bleed. It can occur on the:
It is estimated that about 60,000 new cases of oral cancer are reported annually in India, and five people die from the condition every hour. It is the most common cancer in Indian men and the third most common in women, with roughly 20 in 100,000 people affected.
Oral cancer grows slowly, and the first signs usually don't hurt, so a lot of people don't notice them. However, it's important to look out for
Early diagnosis plays a crucial role in effective treatment. If a mouth sore persists, grows, or is accompanied by pain, bleeding, or difficulty swallowing, it is important to consult a healthcare professional promptly. Paying attention to such small signs can make a significant difference in long-term health outcomes.

Knee replacement surgery has witnessed remarkable advancements over the past few years. Traditionally, total knee replacement was performed as a uniform procedure ("one procedure fits all"), where the entire knee joint was replaced regardless of the extent or location of damage.
However, with the evolution of modern orthopedics, the focus has shifted towards precision and personalized treatment. In this direction, an A La Carte or Modular approach towards patients who need knee Replacement has emerged, which customizes or personalizes the surgery according to the patient’s specific condition.
The term “à la carte” refers to selecting individual items from a menu. In knee replacement surgery, it means replacing only the damaged portion of the joint instead of the entire knee.
The knee is anatomically divided into three compartments:
In many patients suffering from osteoarthritis, the disease affects only one or two of these compartments—most commonly the medial compartment. In such cases, replacing the entire knee may not be necessary. Modular implants allow surgeons to selectively treat the affected area while preserving healthy bone and ligaments.
The à la carte technique helps preserve the natural structure of the knee while effectively treating only the damaged portion, resulting in better and more natural functional outcomes for patients.
However, this approach is not suitable for all patients. It is generally not recommended in inflammatory conditions such as rheumatoid arthritis.
In Total Knee Replacement (TKR), all three compartments of the knee are replaced, making it an effective solution for advanced and widespread arthritis.
In contrast, Modular Knee Replacement offers a more targeted approach:
This selective treatment helps maintain the knee’s natural structure and function.
For carefully selected patients, this technique offers several important benefits:
Not every patient is suitable for this procedure. Proper patient selection is one of the most critical factors in ensuring the success of this procedure. Ideal candidates typically include people:
When performed in the right patient, modular knee replacement delivers excellent long-term outcomes (90 to 95 per cent survivorship for 15 years). Its success largely depends on accurate patient selection and flawless surgical expertise.
In some cases, if arthritis progresses in the remaining compartments over time, conversion to total knee replacement can still be done. However, this is relatively uncommon when proper indications are followed.
Robotic-assisted surgery has further enhanced the precision of this technique. It enables:
Conclusion
Ala Carte or Modular Knee Replacement represents a significant shift toward personalized orthopaedic care. Instead of a "one-size-fits-all " approach, surgeons can now tailor treatment based on the patient’s anatomy and disease pattern.
For many patients, this means less invasive surgery, faster recovery, improved function, and a more natural-feeling knee. Individuals experiencing persistent knee pain are advised to consult an orthopaedic specialist early to determine the most appropriate treatment option.

Beyond lung cancers, air pollution fine particulate matter (PM2.5) is increasing mortality for breast as well as liver cancers, according to a global study led by the Union for International Cancer Control (UICC), including researchers from the Indian Council of Medical Research (ICMR).
The important study showed that long-term exposure to PM2.5 increases the overall risk of developing cancer and the chances of dying from it compared with those living in cleaner environments.
For every 10 micrograms per cubic meter (µg/m³) increase in PM2.5 exposure, the overall risk of cancers increases by more than 11 per cent. At the same time, the risk of death also increases by more than 12 per cent for every 10 µg/m³ increase in PM2.5 exposure.
The researchers argued that while other common risk factors like tobacco and alcohol are being targeted with notable progress, air pollution is silently eroding the gains being made.
“We have made huge strides in reducing deaths from cancer, but polluted air is silently undermining that progress. It is a risk people cannot opt out of, and one that disproportionately affects women, children, and people living in poverty,” Cary Adams, CEO, UICC.
“The cancer community continues to make progress in addressing other major risk factors, including tobacco use, alcohol consumption, and viral, bacterial, or parasitic infections such as HPV and HBV that cause cervical and liver cancers. It is increasingly clear that air pollution must also be recognized as a major and preventable factor that increases the risk of developing cancer and of dying from the disease,” added Dr Elisabete Weiderpass, Director, IARC.
The study, based on data from 42 meta-analyses and systematic reviews published between 2019 and 2024, showed significantly strong associations for liver, colorectal, and breast cancers.
As per recent data from the International Agency for Research on Cancer (IARC), PM₂.₅ exposure contributes to 434,000 lung cancers per year, accounting for more than a quarter of preventable lung cancers in women and nearly one in six in men.
In addition to lung cancer risk, the study noted that the rising levels of PM2.5 are associated with

According to the researchers, people living in low- and middle-income countries bear the greatest overall burden. These countries frequently lack the resources to reduce pollution at source or to provide timely access to cancer prevention, diagnosis, and treatment.
The challenge is compounded by the projected rise in global cancer cases, expected to increase from 20 million in 2022 to 35 million by 2050. People at risk include:
The researchers underscored that the evidence presented in the report is already sufficient to justify decisive action to reduce exposure to polluted air. They called upon policymakers to make required changes across energy, transport, industry, and urban planning to reduce the risk of cancer from air pollution.
The study urged the need for properly implementing effective interventions that are well-established. These include:
