Walking is one of the best ways for older adults to get the recommended 150 minutes of moderate-intensity aerobic exercise per week. But to ensure people get the most from their walking workouts, they need to focus on intensity. One way to do this is with target heart rate. A typical target heart rate for moderate-intensity exercise is between 65% and 75% of a person’s calculated maximum heart rate. Improving walking form and doing interval workouts can help increase speed and thus intensity.

Men can overcome the barrier of back pain in the bedroom by trying different sexual positions and adjusting their intensity and frequency.

A 2025 study suggested that people with sedentary jobs are at higher risk of developing insomnia, which can persist for many years.

Surgery is usually warranted when bunion pain becomes disabling, a skin ulcer develops, or it’s necessary to prevent a bunion from dislocating the second toe. However, recovery can be long and painful, and there’s no guarantee that bunions won’t come back. Prior to surgery, it might help to use strategies that reduce bunion pain, such as adding cushioning to shoes, stretching shoes where a bunion rubs against them, getting roomier shoes or shoes made with stretchy fabrics, and using toe spacers.

In a 2025 Harvard study of more than 133,000 people followed for four decades, those who ate the most red meat each day (a quarter-serving or more) had a 13% higher risk of developing dementia later in life, compared with people who ate the least.

A 2025 analysis suggested that GLP-1 medications used for diabetes and weight loss are associated with lower risks for an array of conditions, but that they increase risks for several others.

Spending time alone with energetic young grandchildren can be physically challenging. It puts grandparents at risk for falls and injuries. It will benefit grandparents to improve their balance and do some muscle strengthening so they can lift or carry squirmy children and also get up and down from a chair or the floor while playing with kids. If children run off while in a grandparent’s care, the grandparent should be wary of obstacles in the path to catch up to them, such as footstools or toys indoors and uneven terrain outdoors.

Blood pressure problems might contribute to glaucoma, a condition that damages the optic nerves and causes vision loss. If blood pressure is too low, for example, blood flow to the optic nerves might decrease. That could deprive the optic nerves of oxygen and nutrients, resulting in nerve damage. High blood pressure might also reduce blood flow to the optic nerves, by damaging the blood vessels that supply the nerves. If glaucoma gets worse despite treatment, blood pressure should be considered as a factor.

A 2025 study addressed the role of genes versus lifestyle habits and life circumstances in influencing a person’s health. Researchers found that genes seemed to have a stronger influence than lifestyle and life circumstances for some diseases, including dementia, macular degeneration, and certain cancers. For other diseases, such as atherosclerosis involving arteries of the heart and brain, rheumatoid arthritis, and diseases of the lung, heart, and liver, lifestyle and life circumstances had a stronger influence than genes.

Diverticula—little pockets that develop in the lining of the colon—can become inflamed or infected and cause bloating, diarrhea, constipation, and pain in the lower left abdomen. The problem, called diverticulitis, might go away on its own, but first-time sufferers should report symptoms to the doctor right away. People with a history of diverticulitis can likely wait a day or two, but then call a doctor if symptoms don’t improve. Treatment for diverticulitis ranges from rest, a clear liquid diet, and antibiotics to hospitalization or surgery.
