What do you do if you've begun receiving those birthday cards poking fun of your advancing age? If you're Dr. Andrew Weil, you calmly take stock of the facts, avoid anti-aging cures (you definitely don't do Botox) and pay more attention to your diet, mental acuity and spiritual life.

And you write another book.

Weil, the chief guru of integrative medicine in the United States, is back in the spotlight promoting his new book, "Healthy Aging: A Lifelong Guide to Your Physical and Spiritual Well-Being."

The Harvard-trained physician, an expert on healing traditions in other parts of the world, has long advocated a blend of Western and alternative medicine and now has 10 books, a Web site and a monthly newsletter to his name. His new book is No. 7 on the Los Angeles Times best-sellers list for nonfiction.

His recommendations — and no-nonsense, practical approach — made a hit with a University of California-Los Angeles audience members recently. They packed a ballroom, clutching his book and peppering him with personal questions about eczema, kidney cancer, supplements and fasting.

We asked Weil, director of the Program in Integrative Medicine at the University of Arizona College of Medicine, about his outlook on aging.

Q. You urge people to accept the inevitability of aging. Does that mean we can't do much about it?

A. We can't do anything about the aging process. We cannot turn back the clock. We cannot grow younger, despite what a lot of people tell us. I think we can do a lot about remaining healthy as we get older.

Q. Describe someone who has a healthy attitude toward aging.

A. I wrote in the book about my visits to Okinawa (at the southernmost tip of Japan). And the oldest old people I saw there bound up to you and the first thing they say is, 'Hi. My name is ... I'm 97. How old are you?' And they are proud of being old. They are healthy, and to me, are beautiful. They haven't used Botox, and they haven't had face-lifts. ... They have the good fortune to live in a society where the old are valued and honored.

Q. That's not our society, is it?

A. I think we are at the opposite extreme. I think we have gotten more and more off the beam in the past 30 years or so.

Q. Has anti-aging medicine (with its experimental treatments such as hormones, cellular injections and caloric restriction to delay the aging process) produced some valuable discoveries?

A. No, I don't think so. (Anti-aging advocates) dispense some good information about preventive health and about proper nutrition. But I think, in general, the products and services that they recommend are ... a waste of money, and at worst, potentially dangerous. Moreover, I think the existence of anti-aging medicine is a vast distraction from what should be the important goal, which is learning how to age gracefully, how to live long and well, and how not to get sick.

Q: What are some aspects of our culture that lead us to believe in anti-aging medicine?

We are obsessed with youth. We are obsessed with appearance. The old are marginalized in our culture. Marketers target a 20-to-49 demographic. The entertainment industry markets to that, and the old are considered not worth it. I think this is the perfect moment to try to change this, because the baby boomers are going to start turning 60 next year, and they are a very large and influential segment of the population. I don't think they're going to settle for the models of aging that previous generations have bought into.

Q. You have introduced a line of skin-care products designed to improve skin texture. Doesn't this contribute to the emphasis on appearance?

A. These are emphatically not anti-aging products. They are anti-inflammatory products and they are, I think, quite novel out there in the American market. They use ingredients, such as these Asian mushrooms, which have not been used in skin-care products. ... My main motivation for doing products ... is to develop a revenue stream to support integrative medical education. My profits from this go to a foundation which is giving grants to institutions doing integrative medical education.

Q. Why is taking fish oil supplements so helpful?

A. Most people in this culture are deficient in omega-3 fatty acids. That has huge consequences on long-term health: cardiovascular health, mental health. And because of the concerns about fish today, I think people need to be very careful about which fish they eat. I think a more reasonable alternative for many people might be to take fish oil supplements, which are distilled and free of contaminants. I think it is especially important for kids.

Q. Are so-called senior moments something that everyone begins to experience?

A. Probably. The key is how much anxiety you have about them. There are many things we can do to protect memory. I think that starts with good nutrition especially, again, with omega-3 fatty acids in the diet, and with containing inflammation, because Alzheimer's begins as an inflammatory process. I'm very interested in turmeric (a spice with anti-inflammatory properties) as an Alzheimer's preventive. And I'm very interested in mental activities that could be protective.

Q: What is the single most effective step we can take to influence how we age?

A: I think it's in the area of attitude. I'm really trying to change attitudes about aging and looking for the positive attributes of aging. To me, that includes things like increased wisdom, increased life experience, maturity, depth of character, better equanimity, increased creativity — all those things for which older people are honored in other cultures.
