Some small studies have suggested that too much vigorous exercise might harm your heart, perhaps by triggering heart rhythm changes or other problems. New evidence allays this concern. In fact, the more fit you are, the longer you may live. For the study, researchers reviewed data from more than 122,000 people who underwent exercise treadmill testing from 1991 to 2014. Based on the findings, they divided the subjects into five performance groups: elite, high, above average, below average, and low. Elite performers — who had fitness levels comparable to endurance athletes — had the lowest risk of dying of any cause during the follow-up period, which averaged just over eight years. The survival benefit was most notable among people ages 70 or older and those with high blood pressure. According to the study authors, there does not appear to be an upper limit of fitness above which a survival benefit is no longer seen. They published their findings online Oct. 19, 2018, in JAMA Network Open.

Preparing your own plant-based meals — focused on beans, grains, and veggies — is easier than you think.

Eating more plant-based foods has many advantages, especially for your heart. But even with the best of intentions, many people find the transition to plant-centric meals a little daunting. Take for instance the daily dilemma of deciding what's for dinner. Where do you even begin?

Instead of trying to cook an entire vegetarian meal from scratch, start with one small step and build from there, says Dr. Rani Polak, founding director of the Culinary Healthcare Education Fundamentals (CHEF) Coaching program at Harvard's Institute of Lifestyle Medicine (see "What is lifestyle medicine?").

Editor's note: This year, we're highlighting legumes on this page. Low in fat but rich in protein and other nutrients, they're a staple of plant-based eating. Starting in February, we'll feature a different legume each month, along with information and recipe tips from different cultures around the world.

But we're starting off with the basics: a simple recipe for cooking dried beans.

Research we're watching

People whose daily diets include at least two servings per day of milk, yogurt, or cheese appear to have a lower risk of heart disease, stroke, or death than people who don't consume dairy products.

The findings, published Sept. 11, 2018, in The Lancet, were based on food questionnaires from more than 136,000 people from 21 countries. After a follow-up that lasted an average of nine years, researchers found that adults who consumed two or more servings of dairy each day had a 22% lower risk for heart disease, a 34% lower risk for stroke, and a 23% lower risk of heart-related death. Observational studies such as this one cannot prove cause and effect. But dairy-based foods contain vitamins D and K, calcium, and other nutrients thought to be good for cardiovascular health. The findings support the benefits of all types of dairy, including full-fat versions. However, current guidelines still recommend nonfat or low-fat milk, yogurt, and cheese, which contain fewer calories and less saturated fat.

These master-level athletes can teach you how to stay fit and healthy.

You're never too old to learn from the experience of others. For instance, master athletes in their 60s, 70s, and even 80s might compete at a higher level than you, but they still face the same age-related challenges.

"You can gain much wisdom from these individuals, such as how to exercise smarter, how to overcome obstacles, and how to stay motivated," says Dr. Adam Tenforde, assistant professor of physical medicine and rehabilitation at Harvard-affiliated Spaulding Rehabilitation Hospital. "They have developed strategies that can be adopted by the average person to help maintain health and reach specific goals."

Q. My skin gets dry and itchy in winter, and there are so many moisturizers available. What should I look for?

A. Dry skin develops when your skin doesn't retain sufficient moisture. This is often a problem in winter when the air both indoors and outdoors has low humidity, as the water content of our skin tends to reflect the level of humidity around it. Fortunately, using a good moisturizer is a simple way to relieve winter dry skin.

Q. I have trouble seeing clearly at night, especially when I drive. Should I change my glasses, or could it be a more serious eye problem?

A. As people reach age 60 and older, trouble seeing at night becomes a typical issue. The problem could be with your glasses or your eyes. Your eyesight might have changed since you were last fitted with glasses, and the change is noticeable only at night. If so, an updated prescription for new lenses may do the trick. Even if your eyeglass prescription is correct, ask your optometrist to add an antireflective coating to your lens to cut down on the glare of headlights of an oncoming car.

There are ways to keep morning stiffness from being a pain.

Ever get that "old man" stiffness in the morning? You know the feeling: the dull, achy, and sometimes painful feeling in your joints — along with the customary grunts and groans — when you first stand and slowly move around.

"It's not known why this happens, especially as people age, but the only common thread is that it occurs after long bouts of inactivity," says Dr. William Docken, a rheumatologist with Harvard-affiliated Brigham and Women's Hospital. "That is why you often feel so stiff when you wake up, since sleeping is when you are inactive for the longest continuous time."

Begin the new year by reviewing where you are now and where you want to go.

This year, don't fall back on the standard resolutions as a way to set goals. Instead, do a health self-assessment. It's a way to measure where you are now, decide what you want to do, and determine how to get there.

"A health self-assessment gathers the vital information you need to begin thinking more about your life and how you want to live," says Susan Flashner-Fineman, Vitalize 360 Coach at Harvard-affiliated Hebrew SeniorLife, a comprehensive wellness program that promotes healthy aging. "It helps identify your life goals, which can vary from something as simple as ensuring you can continue your independent living to something more ambitious, like traveling more."

There's a lot you can do to improve your outcome if you're taking an active surveillance approach to your diagnosis.

About 90% of men diagnosed with prostate cancer have the localized kind, which means the cancer is confined to the prostate gland. And for many, a reasonable approach is active surveillance, in which men choose to monitor their cancer instead of going straight into invasive treatments, such as surgery or radiation therapy.

Active surveillance includes a doctor visit about every six months, most often with a prostate-specific antigen (PSA) blood test and digital rectal exam.
