Q. My wife says I should slow down and retire, but I hope I can work forever. What's your take?

A. It's a question I get asked a lot, from boomers and pre-boomers, and one I've asked myself.

A youthful attitude may lead to better eating and exercising habits.

Plenty of research shows that we tend to exhibit the health behaviors of people around us, and that partners can influence each other's behavior. The influence carries even more weight if an unhealthy partner is making a change for the better. A study published in JAMA Internal Medicine Jan. 19, 2015, found that men and women were much more likely to make positive changes if their partners also changed their health behavior during the same period. The influence on a partner was significant: 67% of men took up physical activity if their wives did, but only 26% became active if their wives did not. The take-home message: get your partner on board if you both need to make healthy lifestyle changes.

Even an hour's exercise a day won't protect you from an earlier death, if you spend most of the rest of your day sitting. That's the verdict of Canadian researchers who pored over data from 47 studies on the effects of sedentary behavior. When they combined the results of all the studies, the researchers found that regardless of their levels of physical activity otherwise, people who sat for long periods had an increased risk of developing a host of diseases. People who sat the longest had a 24% greater risk of dying, an 18% greater risk of heart disease, a 13% greater risk of cancer, and a 90% greater risk of diabetes. The results were published in the Jan. 20, 2015, issue of Annals of Internal Medicine.

A study published in the Jan. 27, 2015, issue of The BMJ challenges the longstanding notion that weight gain protects against postmenopausal fractures. Data from the Women's Health Initiative (WHI) indicate that weight gain, as well as weight loss, is associated with increased risk of fractures in postmenopausal women. The analysis also suggested that which bones were most likely to break depended on whether women have gained or lost weight.

WHI researchers analyzed data on over 120,000 healthy postmenopausal women ages 50 to 79 at the start of the study. Each year, participants were weighed and asked to report fractures of their arms, legs, hip, pelvis, and spine.

Mobility relies on the body's two largest joints, the hips and knees. We ask a lot of both these joints: they must bear our full weight and coordinate movement over a lifetime of standing, walking, running, dancing, and sports. Not surprisingly, hip and knee pain are common complaints, and nearly everyone who lives into old age can expect some trouble with these joints. But taking care of your hips and knees and managing any pain that arises will help you avoid losing mobility as you age.

Q. My doctor, an internist, just retired, and my health plan is asking me to designate a new primary care physician. I'm 75. Would there be advantages to choosing a geriatrician as my new doctor?

A. First, a disclaimer: I am a geriatrician. So my short answer is, "Yes, of course!" But my reasoned, unbiased answer would be, "It depends." If you are a generally healthy 75-year-old woman, a family physician or internist will be able to take excellent care of you. Geriatricians are trained to care for older adults with complex illnesses and are expert in managing the care of people who are frail. Improving your ability to function, and the quality of your life, are the guiding principles of geriatric medicine. We are expert at managing complexity and uncertainty, working with families, and caring for people with serious illnesses who are approaching the end of life. A geriatrician would be a good choice if you have physical or cognitive impairment, if you take a lot of medications, or if your friends and family are involved in your medical care. For people who have several medical problems, we emphasize the role of patient and family preference in making medical decisions, with the patient's goals as our primary focus.

Better support for your spine is key in avoiding neck ache.

Two in three women over age 40 wake up at least once each night because of a full bladder, and nearly half make two or more nighttime trips to the bathroom. But only a quarter of women who get up to urinate during the night say they are bothered by having to do so.

That's the finding from a survey of more than 2,000 northern California women ages 40 and older. Factors that increased the likelihood that a woman woke at night to urinate included older age, past hysterectomy, hot flashes, and use of vaginal estrogen. However, the late-night bathroom breaks weren't caused by an overactive bladder or stress incontinence. The results were published in the January 2015 issue of the journal Obstetrics and Gynecology.

Claiming to feel younger than your age isn't just whistling into the wind. It can also mean you have more years ahead than some of your former classmates. According to a report in the Dec. 15, 2014, issue of JAMA Internal Medicine, older people who felt three or more years younger than their chronological age had a lower death rate compared with those who felt their age or older.

Two researchers at University College London looked at the responses of about 6,500 men and women with an average age of 65 who answered the question, "How old do you feel you are?" About 70% reported that they felt three or more years younger than their years, while 25% felt close to their age, and 5% felt more than one year older than they were.
