A study published online Aug. 8, 2016, by BMJ Open found that volunteering seems to confer greater benefits for general well-being in middle and older age than earlier in life. 

About one in three adults has nonalcoholic fatty liver disease, an often-silent condition closely linked to heart disease.

The largest organ inside your body, your liver performs hundreds of vital functions. It converts food into fuel, processes cholesterol, clears harmful toxins from the blood, and makes proteins that help your blood clot, to name a few. But an alarming number of Americans have a potentially dangerous accumulation of fat inside their livers. Known as nonalcoholic fatty liver disease (NAFLD), this condition is a leading cause of chronic liver disease in the United States—and an increasingly recognized contributor to heart disease.

"NAFLD increases the risk of heart disease independent of other traditional risk factors such as high blood pressure and cholesterol," says Dr. Kathleen Corey, director of the Fatty Liver Disease Clinic at Massachusetts General Hospital. Among people with NAFLD, heart disease is the top killer, accounting for more than 25% of deaths.

Droopy eyelids, known as ptosis, are often a normal occurrence of aging although some neurologic conditions also can cause the condition. Ptosis is not a serious problem unless it interferes with your vision. If this happens, or if your droopy eyelids are bothersome, you can opt for cosmetic surgery to repair your eyelids.

The science of neurogenesis suggests it's possible to create neurons that improve your memory and thinking skills.

There are many aspects of aging you cannot prevent, but surprisingly, memory trouble is not one of them.

"The dogma for the longest time was that adult brains couldn't generate any new brain cells. You just use what you were born with," says Dr. Amar Sahay, a neuroscientist with Harvard-affiliated Massachusetts General Hospital. "But the reality is that everyone has the capacity to develop new cells that can help enhance cognitive functions."

Lower your dependency on medication by altering your perception of pain.

Everyday pain becomes more constant as you age. It can vary from morning aches to occasional joint flare-ups to recurrent episodes that interfere with your life and overall health.

Yet pain has a valuable role. It alerts your systems to potential injury so you can seek treatment. "Pain is similar to blood pressure, which becomes a problem if the levels become too high," says Dr. Jianren Mao, director of the Harvard-affiliated Massachusetts General Hospital Center for Translational Pain Research. "Only when pain becomes intolerable should you resort to medication or other types of treatment."

A mindfulness-based stress reduction program (MBSR) can help control anxiety among men who follow active surveillance for prostate cancer. The wait-and-see approach can make men feel so uneasy about their condition that they opt for treatment with radiation therapy or surgery when it is unnecessary. MBSR not only eases anxiety levels, but also inspires men to be more proactive about their health and adopt lifestyle changes like a proper diet and exercise.

Mindfulness can be an effective adjunct to medication for chronic pain.

For a long time, people with chronic pain have had to make a trade-off—enduring the discomfort stoically or taking medications that pose additional health risks, including dependence and addiction. But in the last few years, medicine has added another approach that has no troubling side effects: mindfulness.

"Mindfulness is basically paying attention to the present moment without judging," says Dr. Sara Lazar, a neurologist at Harvard-affiliated Massachusetts General Hospital. It is a component of many relaxation techniques, including yoga, deep breathing, tai chi, massage, reflexology, journaling, and prayer.

Long-term risks are associated with proton-pump inhibitors, but there are other options for treating acid reflux.

Proton-pump inhibitors (PPIs), which reduce the amount of acid produced in the stomach, are so effective at treating heartburn and ulcers that they've been among the world's top-selling drugs for 25 years. Initially available only by prescription, PPIs, which include omeprazole (Prilosec), lansoprazole (Prevacid), and esomeprazole (Nexium), have been sold over the counter for several years. However, now that millions of people are taking PPIs, the drugs have been linked to an increasing number of health risks, such as fractures, kidney problems, vitamin B12 deficiency, low magnesium, and—most recently—dementia and heart attack.

"These studies—especially those suggesting a relationship to dementia and heart attack—are concerning," says Dr. Jacqueline Wolf, a gastroenterologist and associate professor of medicine at Harvard Medical School and author of A Woman's Guide to a Healthy Stomach: Taking Control of Your Digestive Health.

British researchers tested whether behavioral activation therapy alone is as effective as cognitive behavioral therapy. The results were almost identical for both groups, with two-thirds of each group reporting a reduction of depressive symptoms of at least 50%.
