Socrates may have been the first to equate healthy feet with quality of life when he famously said, "When one's feet hurt, one hurts all over." His observation rings true even millennia later.

"As you age, healthy feet become even more important for staying mobile, active, and safe," says Dr. Kevin Reimer, a podiatrist with Harvard-affiliated Beth Israel Deaconess Medical Center. "When it hurts to walk, you cut back on activities that you enjoy and that keep you healthy."

Here's a possible strategy to boost memory—exercise four hours after you learn something. In a study published in the July 11, 2016, Current Biology, researchers found that exercise after learning may improve your memory of the new information, but only if done in a specific time window.

When you think of a holiday, your medicine cabinet probably doesn't come to mind. But for people who take medications long-term, a drug holiday—a break from a medication for days or even years—may be helpful, for some medicines. "For some people, it gives the body a chance to recover the systems that have been suppressed by the drug," says Dr. Michael Craig Miller, assistant professor of psychiatry at Harvard Medical School.

Q. I love dried fruit and thought it was healthy. But I hear that you gain a lot of weight eating dried fruit, which is not healthy. What's the truth?

A. The truth is that the actress and comedian Mae West was wrong when she allegedly said "Too much of a good thing ... can be wonderful!" Food contains calories, and eating too many calories-even of healthy foods-leads to weight gain. But there are healthy calories and unhealthy ("empty") calories, and fruit is a healthy source of calories. That's as true of dried fruit as fresh fruit.

The new Nutrition Facts labels will list “added sugars” in a serving of food. Until the labels appear, one should look for sugars such as dextrose and sucrose on a label’s list of ingredients.

Strength training, weight-bearing exercise, a healthy diet, and medication can help.

An estimated 10 million people in the United States are coping with the brittle, fragile bones of osteoporosis—a disorder that causes severe bone loss. It's most common in women, and the risk is higher in those who are thin, age 50 or older, or of Caucasian or Asian descent. It also occurs in men, who make up about 20% of osteoporosis cases. The condition puts a person at a high risk for bone fractures, disability, loss of independence, and even death. That's why it's important to make your bones as strong as possible. "There are many ways to build bone mass, and the people who do tell us they feel stronger and more capable on their feet," says Rachel Wilson, a physical therapist at Harvard-affiliated Brigham and Women's Hospital.

There isn't one magic way to build bone mass. It takes a number of the following strategies.

As we reported in August 2016, the FDA is encouraging the food industry to cut back on added sodium in commercially processed and prepared food. It's a good reminder for all of us that too much salt in the diet is risky for health. How much is too much? "It's controversial, although I don't think anyone is in favor of unlimited salt intake," says Dr. Randall Zusman, a cardiologist with Harvard-affiliated Massachusetts General Hospital.

When the doctor says you have obstructive sleep apnea (OSA), you'll likely hear about the gold standard in treatment: continuous positive airway pressure (CPAP), which uses forced air, pushed through a tube connected to a face mask, to keep your airway unblocked. Yet many people have trouble adjusting to a bulky CPAP mask. "We often see people who say they tried CPAP and didn't like it, and now it's been years since they've had treatment," says Dr. Stuart Quan, the Gerald E. McGinnis professor of sleep medicine at Harvard Medical School.

You may be able to adjust to CPAP by trying relaxation exercises, practicing wearing the mask during the day, and gradually increasing CPAP pressure. But if it doesn't work out, you do have alternatives.

Look for gadgets or services that get people moving.

During the holidays, or at any time of year, a gift that benefits health can have a lasting impact. It may be especially helpful to someone who wouldn't normally purchase such an item or doesn't know about available options. A few guidelines to keep in mind: "The gift should be easy to use. Consider the receiver's interests, and accommodate previous injuries, surgeries, medical conditions, or functional limitations," says Dr. Clare Safran-Norton, a physical therapist at Harvard-affiliated Brigham and Women's Hospital.
