Healthy Aging

Can you recommend nonsurgical treatments to help my face look younger?

DEAR DOCTOR K: I'm 65, and my face is starting to look old. Can you recommend nonsurgical treatments to take a few years off my face?

DEAR READER: Our faces age along with the rest of us. The difference is that our face is the part of ourselves that we look at most often -- and that others look at most often. Some people accept these changes; others fight them every step of the way. But there's also a middle road for people who prefer to make relatively small tweaks that can make a noticeable difference.

How does physical exercise improve brain health?

DEAR DOCTOR K: You say that physical exercise helps to improve brain health, but it's not obvious to me how that could be. Do researchers understand exactly how exercise helps the brain?

DEAR READER: I understand why that's puzzling. It's easier to see how regular moderate exercise could protect against heart disease, for example. The heart is a muscle, and exercise makes the heart exercise.

What’s considered normal aging when it comes to sex?

DEAR DOCTOR K: My wife and I are in our 70s. Sex is not what it once was. Is there anything "natural" I can do to improve sex? I don't want to take pills. What's normal aging when it comes to sex?

DEAR READER: As a man in the last half of his life, I would like to be able to tell you that nothing changes. However, even in healthy men, sexuality changes over time. It's often a gradual, almost unnoticeable process that usually begins in a man's 40s.

How can I tell if my complaints are a consequence of aging or an actual problem?

DEAR DOCTOR K: Every time I complain about a new medical issue, my husband says, "You're 84. What do you expect?" How do I know if my complaints are just a consequence of aging or if there's an actual problem?

DEAR READER: I'm not 84, but I ask myself that question regularly. You don't have to be a doctor to understand that new symptoms develop as we age. But some changes aren't a normal part of the aging process. I'll discuss some common age-related health changes, as well as changes that suggest there might be a problem.

Are there any natural remedies for hot flashes?

DEAR DOCTOR K: I'm afraid to take hormone therapy for my menopausal hot flashes. Are there any natural remedies that work?

DEAR READER: Natural remedies can help for hot flashes, but hormone therapy is helpful more often. For that reason, I'll come back to the pluses and minuses of hormone therapy after answering your question.

Can growth hormone help fight the effects of aging?

DEAR DOCTOR K: A friend of mine who is in her 70s is getting growth hormone shots. She says it fights aging. I'm dubious that anything can fight aging and worry about side effects. Am I just old-fashioned?

DEAR READER: Well, you certainly are right to ask these questions. If there was a treatment that could slow aging and was risk-free, I guess we'd all take it.

What is executive function?

DEAR DOCTOR K: An aging friend was told he has problems with "executive function." So, of course, I'm wondering what that is, if I also could have that problem, and what can be done about it. Could you explain?

DEAR READER: Executive function refers to a set of mental attributes required to make choices, plan, initiate action and inhibit impulses. While "executive function" is a term used to describe attributes of business executives, it applies to everyone.

Should I change my foot care routine as I get older?

DEAR DOCTOR K: As I've entered my 60s, I've noticed that my toenails are thicker and the skin on my feet is drier. Should I change my foot care routine?

DEAR READER: Just like the rest of your body, your feet change with age. By age 50, you may have lost nearly half of the fatty padding on the soles of your feet. To compensate, you may want to add over-the-counter cushioning inserts to your shoes for additional padding.

What can we do to ease my mother’s transition to assisted living?

DEAR DOCTOR K: We've finally convinced my mother to move to an assisted living facility. After spending the past five decades in her current house, she is very nervous about the move. What can we, and she, do to make the transition easier?

DEAR READER: Assisted living facilities are designed for people who can't live on their own because they need help with the tasks of everyday living. The facilities generally provide meals, help with taking medication, housekeeping, laundry and activities. They are not meant for people who need round-the-clock nursing care.
