Forget Old Age, Think New Stage
What's Your True Age?
What's Your Body Age?
Yes, everybody ages. And every body changes. Like
it or not, chronologically speaking, when you finish
reading this sentence, you’ll be six seconds or so further
away from the date on your birth certificate.
In a culture obsessed with youth, the thought that
the clock is ever ticking strikes fear in the hearts of
many. Uncomfortable with the idea of getting older,
many of us live in denial through our 20s and 30s, then
do all we can to maintain the appearance of youth in our
40s and beyond. We’ll douse our hair in dye, furiously rub
in “antiaging” cream and spend years telling ourselves
that we don’t look a day over 29. And, sure, those strategies might calm our fears for the short term, but they
help little when it comes to reinforcing the foundations
of our health and vitality as the years roll on.
Luckily, research has shown that the pace of the
aging process can be influenced — by you. Your chronological age (indicated by the birth date on your driver’s
license) does not entirely dictate your biological age
(the age you actually look, feel and function at). And,
happily, the dimension and character of the discrepancy
between those numbers are largely in your control.
By taking some commonsense steps now, you can
increase your chances of looking and feeling great many
decades hence. You can also decrease the time you spend contending with the ill health, pain and compromised
quality of life that too often accompany later years.
Wherever you are on life’s aging continuum, there
are proven ways to maximize your physical and mental
health and increase not only your chance at a longer life,
but, more importantly, the quality of your longevity.
Better Your Biomarkers
We commonly associate the concept of aging with its vis-
ibleeffects, but in fact, the most significant causal factors
of aging occur deep within our bodies. Both the causal and
symptomatic factors of physiological aging, termed “bio-
markers,” have been the object of increased popular
interest in recent years, particularly since authors William
Evans, PhD, and Irwin Rosenberg, MD, introduced the con-
ceptto the public in their best-selling book, Biomarkers:
The 10 Keys to Prolonging Vitality (Fireside, 1992).
Hundreds of recognized biomarkers exist in the
body (and countless more are likely yet to be identified),
and scientists are still not entirely clear on the exact role
they play in the aging process. Some, like graying hair
and wrinkling skin, appear to be evidence of aging, while others are conditions that actually advance aging by triggering other age-related factors.
Loss of lean muscle (a biomarker), for example, leads
to diminished muscle strength (also a biomarker), which in
turn increases your body-fat percentage (another biomark-
er),thereby decreasing resting metabolic rate (biomarker
again), which can contribute to compromised arterial
health — one of the most important biomarkers of all.
Lifestyle choices can make or break your biomarkers,
insist Evans and Rosenberg. No matter what your age,
you markedly improve your current health and fitness by
taking steps to improve the 10 most significant biomarkers. You can also delay and diminish the time you’ll
spend in what the authors refer to as the “Disability
Zone” — the years preceding death during which many
people suffer invalidism, dependency, frailty and pain.
The best part is, you can upgrade your status in
each of the biomarkers (a process referred to as “bio-intervention”) simply by adjusting your daily habits.
TOP 10 BIOMARKERS
1. Muscle Mass — The amount of lean muscle tissue
on your body.
2. Strength — Your ability to support, move and
resist weight.
3. Basal (or Resting) Metabolic Rate — The
baseline rate at which your body burns calories by
metabolizing food and tissue into energy.
4. Body-Fat Percentage — Your body’s fat-to-
muscle ratio.
5. Aerobic Capacity — Your body’s ability to process
oxygen from the air and move it into your bloodstream and throughout your entire system.
6. Blood-Sugar Tolerance — Your body’s ability
to control and process glucose (sugar) from food and
distribute it via your bloodstream to be converted
into energy or fat.
7. Cholesterol/HDL ratio — The ratio of LDL
(bad cholesterol) to HDL (good cholesterol) in
your bloodstream.
8. Blood Pressure — The level of pressure exerted
by the blood on the walls of the blood vessels.
9. Bone Density — The density of the mineral content
in your bones.
10. Body-Temperature Regulation — Your body’s
ability to maintain its internal temperature.
A quick glance at the list confirms that the top biomarkers for healthy aging mirror the expert advice for
maintaining physical health at any age. That’s because
many of the symptoms we’ve come to associate with
growing older (like frailty, weakened immune system,
loss of strength) are often less a product of the natural
passage of time and more the result of years of chronic
physical neglect caused by stress, lackluster eating and
sleeping habits, inconsistent exercise, and the like.
Accepting this truth can unearth as many fears and
anxieties as it allays. While it’s a relief to learn that the
physical decline of aging is not an abstract absolute,it’s uncomfortable to acknowledge the fundamental role
we play in the velocity of our own undoing. Essentially,
much of what we think of as “aging” is really the
compounded result of years of bodily neglect.
Fortunately, healthy-aging experts insist, the
opportunities to choose a future of vitality and longevity
over decline and decrepitude present themselves to each
of us day by day. It’s never too late to start making
healthy changes. And there’s no easier way to motivate
yourself to make those healthy choices
than by directly observing their profound
impact on your health right now.
If you want to get a better sense of
your current “real age” as indicated by
your biomarkers, check out the free health
analyses available at www.realage.com.
Built on the success of the best-selling
book RealAge (HarperCollins, 2001) by
healthy-aging guru Michael Roizen, MD, the Web site
calculates your real-age number based on 137 biomarkers
and other factors that can influence your rate of aging
(for details, see “What's Your True Age?”). The
site also offers tailored consumer
health information based on
your particular set of genes,
health history and habits.
The fun (or perhaps
sobering) part is seeing
how the recommended
changes could affect
your biological age.
Eat Younger Every Day
According to integrative health physician Andrew Weil,
MD, the role that balanced nutrition plays in supporting
healthy aging cannot be overstressed. As he explains in his
bestseller Healthy Aging: A Lifelong Guide to Your Physical
and Spiritual Well-Being (Knopf, 2005), many of the biomarker breakdowns associated
with aging — from a weakened immune system to cholesterol
imbalance — can be attributed to inflammation.
Inflammation is a natural component of the body’s
healing system, indicating increased immune activity
in an area of the body that is injured or ill. But
the inherent power of inflammation is also potentially
destructive; too much can cause tissue damage and
disease. To regulate the inflammatory process, the
body relies on families of hormones that
either upregulate (intensify) or
downregulate (diminish) it.
Food directly affects these hormone levels, either activating or inhibiting
internal inflammation.
To encourage the latter, Weil developed the Anti-
Inflammatory Diet, a way of eating that he believes will not
only reduce your risk of developing age-related illnesses
such as cancer and cardiovascular and neurodegenerative
disease, but will also support optimum nutrition and
overall health, increase energy levels, boost immunity,
and even give you better-looking skin and hair.
Here are the basics of Weil’s Anti-Inflammatory Diet
(the complete guide can be found in Appendix A of
Healthy Aging and is also accessible online to paying
members of www.healthyaging.com):
EAT A WIDE VARIETY OF FRESH FOODS, including lots of
fruits and veggies from all over the color spectrum.
Avoid processed and fast foods.
MOST ADULTS NEED TO CONSUME between 2,000 and
3,000 calories a day (women and smaller and less active
people need fewer calories). Ideal caloric breakdown: 40
to 50 percent carbohydrates, 30 percent fat, 20 to 30
percent protein. Aim to include a balance of healthy
carbs, fats and protein in every meal.
CHOOSE CARBS with low-glycemic loads, like whole
grains (excluding whole-wheat-flour products), beans,
winter squashes and sweet potatoes. Avoid wheat flour
and sugar, especially bread and most packaged snack
foods (including chips and pretzels).
CONSUME FATS in a ratio of 1:2:1, meaning one measure
of saturated to two measures of monounsaturated to one
measure of polyunsaturated fat. Strictly avoid all products
made with partially hydrogenated oils of any kind.
Good fats include: extra-virgin olive oil, avocados and
nuts (especially walnuts, cashews and almonds). Seek
out omega-3 fatty acids, available in salmon, sardines,
herring, black cod, fortified eggs, hemp seeds, flaxseeds
and walnuts.
AIM FOR FIBER, 40 grams daily. Good choices include
fruit (especially berries), veggies and whole grains.
DRINK SIX TO EIGHT GLASSES of pure water a day.
Substitute high-quality green, white or oolong tea
for coffee.
Brain Boosters for Life
Scientists once believed brainpower peaked at early mid-
dle age. Now they know better. In a January 2006 Time
magazine article, writer Jeffery Kluger reported that
recent studies have shown that far from slowing down
during the course of a lifetime, the aging brain begins to
use new cognitive systems and to cross-index existing
ones in new ways. At UCLA, for example, neurologists
studying myelin, the fatty sheath of connective tissue
that helps conduct nerve signals throughout the brain,
have found that myelin development peaks in healthy
adult brains between the ages of 45 and 50. The scientists
postulate that this may allow older brains faster
processing and information-retrieval speeds than younger
brains, whose myelin stores have yet to fully mature.
In fact, older brains operate quite a bit differently
than their younger counterparts, according to neuro-
scientist Roberto Cabeza, PhD, associate professor of
psychology and brain sciences at Duke University’s
Center for Cognitive Neuroscience. He found that older
brains increasingly use both the left and right hemispheres
of the prefrontal cortex in tandem, rather than working
independently of each other, like younger brains do. While
Cabeza speculates that this phenomenon may be a trick
the brain uses to compensate for age-related cognitive
decline, the integration of the hemispheres can sometimes
become so efficient that the older brain’s reasoning and
thought processes operate better than ever.
Findings like these have led some experts to conclude that the brain at midlife — a stage increasingly defined as the years from 40 to 60 — is far more limber
an organ than previously realized. It may even rival the
young brain for qualities like temperament, comfort with
ambiguity and the ability to interpret meanings.
That’s more support for our “with age comes wisdom”
truism. It’s important to note, though, that the brain
works a lot like a muscle. The more you use it, the
healthier it becomes, say experts like Gene D. Cohen,
MD, PhD, author of The Mature Mind: The Positive Power
of the Aging Brain (Basic Books, 2005), and Sandra Cusak,
PhD, and Wendy Thompson, MA, the authors of Mental
Fitness for Life (Bull Publishing, 2006). Just as working
out helps you stay in top physical shape, mental-fitness
routines boost your brain’s power, strength and stamina.
Cusak and Thompson developed their seven-step
Mental Fitness for Life course based on current research
on cognitive function in the aging brain and their own
research with the senior residents of Century House, a
2,100-member recreation center for seniors on the
Canadian west coast. No matter your age, whether 33 or
103, insist Cusak and Thompson, by challenging your
brain in this way, you can support deft and dexterous
brain functioning for years to come:
1. Set Goals: Goal setting has rarely been a focus for
personal development work with people over 50,
write Cusak and Thompson. But research suggests that
those in their “third age” who undertake goals in an
entirely new area, such as an untried foreign language or
musical instrument, enjoy special brain-boosting benefits.
2. Power Think: “Simply put, power thinking means
out with the old beliefs and in with the new,”
explain the authors. It can be accomplished by identifying limiting beliefs about yourself, challenging them
and replacing them with new beliefs about your potential for limitless growth as you age.
3. Be Creative: New research suggests that people
can develop their creativity into later life, say
Cusak and Thompson. And creativity is not restricted
to just artistic expression: It’s about bringing anything
new — from ideas to ways of being in the world —
into existence.
4. Accentuate the Positive: Having a positive attitude is critical to healthy brain aging. “Research
tells us that optimistic people live as much as six years
longer,” says Cusak. Optimism can be cultivated, even by
sworn pessimists. By actively working to see the positive
in every situation, you can gradually adjust your outlook
on life in ways that support both brain and body health.
5. Learn to Remember, Remember to Learn: You
can support your memory by adopting the “lifelong
learning” approach. “Learning new things causes the
dendrites [a component of neurons] to grow and branch
wildly, improving brain power,” write the authors.
6. Speak Your Mind: Share your well-earned perspective with others. Consider starting a “conversational
salon” or “philosophers’ cafe” in your community.
7. Have a Plan: The final step to ensuring the Mental
Fitness for Life plan is having a strong strategy to
implement and support the first six steps. The authors
advise an ongoing assessment and adjustment approach:
“Tailor-make your mental fitness program daily, weekly,
monthly and yearly,” they write. “Change it as you
change yourself.”
Forget Old Age, Think New Stage
One of the funny quirks about human aging is, statistically speaking, the longer you live, the longer you’re
likely to live. For example, a child’s life expectancy
increases by the time it reaches its first birthday.
If you’ve made it to late
adulthood, the odds of
living to a ripe old age
are decidedly in your
favor. All the more reason
to safeguard the quality
of those extra years. (For
more on that, see the “Into the Wild Blue Yonder" Web Extra!)
We now know that
the physical and mental
decline long associated
with aging is less a fated
guarantee and more a
single outcome in a world
of possibilities. “Yes, aging
can bring frailty and suf-
fering,” Weil writes in
Healthy Aging, “but it can
also bring a depth and
richness of experience, complexity of being, serenity,
wisdom, and its own kind of power and grace.”
Aging gracefully, it seems, requires both pragmatically accepting the aging process and proactively
integrating the approaches best proven to maximize
health at any age. No, you can’t turn back the clock, and
you’re not going to live forever. But by making smart
decisions today, no matter how old you are, you can
ensure your chance of becoming the person with whom
you’ll want to spend the rest of your life.

What's Your True Age?
According to aging experts, you are, in many ways, as
young as the health of your habits. RealAge is a system
of measuring your biological age (as opposed to your
calendar one) based on 137 factors that can influence
your rate of aging. To begin to get an idea of what age
you look, feel and function at, answer the following
questions (the full assessment is available free at
www.realage.com):
DO YOU GET YOUR VITAMINS? Regularly taking
supplements of vitamin C (1,200 mg/day), vitamin E
(400 IU/day), calcium (1,000–1,200 mg/day), vitamin
D (400–600 IU/day), folate (400 mcg/day), and vitamin
B6 (6 mg/day) can cut six years from your RealAge.
Check your multivitamin to see how it compares.
DO YOU HAVE A HANDLE ON STRESS? Periods of
intense stress can add as much as 32 years to your
RealAge. But maintaining good stress-reduction strate-
gies and strong social support networks wins back as
many as 30.
DO YOU SMOKE? Smoking adds eight extra candles
to your RealAge. The good news? Quitting will knock
seven right off.
DO YOU LISTEN TO YOUR DENTIST? Daily flossing
and brushing cuts 6.4 years from your RealAge. Left
unchecked, the plaque on your teeth is the same bacteria
that leads to inflammation and clogging of the arteries,
while periodontal disease and tooth loss puts your
immune system at risk.
ARE YOU ACTIVE? Even a small amount of exercise —
as little as two 20-minute walks a day — can shave five
years off your RealAge.
DO YOU GET YOUR FIBER? Getting at least 25 grams
offiber a day can make your RealAge 2.5 years younger.
(Andrew Weil, MD, recommends as much as 40 grams.)
DO YOU LAUGH? It’s no joke — laughing a lot
reduces stress, strengthens the immune system and can
deduct as many as eight years from your RealAge.
DO YOU LOVE TO LEARN? Becoming a lifelong
learner can reduce your RealAge as much as 2.5 years.
ARE YOU CURRENT ON YOUR CHECKUPS?
Seeking quality medical care and managing chronic
conditions wins you back 12 RealAge years.
DO YOU BUCKLE UP? Wearing your seat belt and
staying within 5 mph of the speed limit can make your
RealAge as much as 3.4 years younger.
What's Your Body Age?
Many health clubs offer members free or low-cost BodyAge assessments in order to help them establish a baseline measurement of several key health and fitness indicators. The assessment provides you with your current BodyAge score, as well as a recommended fitness program.

to just artistic expression: It’s about bringing anything
new — from ideas to ways of being in the world —
into existence.
4. Accentuate the Positive: Having a positive attitude is critical to healthy brain aging. “Research
tells us that optimistic people live as much as six years
longer,” says Cusak. Optimism can be cultivated, even by
sworn pessimists. By actively working to see the positive
in every situation, you can gradually adjust your outlook
on life in ways that support both brain and body health.
5. Learn to Remember, Remember to Learn: You
can support your memory by adopting the “lifelong
learning” approach. “Learning new things causes the
dendrites [a component of neurons] to grow and branch
wildly, improving brain power,” write the authors.
6. Speak Your Mind: Share your well-earned perspective with others. Consider starting a “conversational
salon” or “philosophers’ cafe” in your community.
7. Have a Plan: The final step to ensuring the Mental
Fitness for Life plan is having a strong strategy to
implement and support the first six steps. The authors
advise an ongoing assessment and adjustment approach:
“Tailor-make your mental fitness program daily, weekly,
monthly and yearly,” they write. “Change it as you
change yourself.”
Forget Old Age, Think New Stage (Back to Top)
One of the funny quirks about human aging is, statistically speaking, the longer you live, the longer you’re
likely to live. For example, a child’s life expectancy
increases by the time it reaches its first birthday.
If you’ve made it to late
adulthood, the odds of
living to a ripe old age
are decidedly in your
favor. All the more reason
to safeguard the quality
of those extra years. (For
more on that, see the “Into the Wild Blue Yonder" Web Extra!)
We now know that
the physical and mental
decline long associated
with aging is less a fated
guarantee and more a
single outcome in a world
of possibilities. “Yes, aging
can bring frailty and suf-
fering,” Weil writes in
Healthy Aging, “but it can
also bring a depth and
richness of experience, complexity of being, serenity,
wisdom, and its own kind of power and grace.”
Aging gracefully, it seems, requires both pragmatically accepting the aging process and proactively
integrating the approaches best proven to maximize
health at any age. No, you can’t turn back the clock, and
you’re not going to live forever. But by making smart
decisions today, no matter how old you are, you can
ensure your chance of becoming the person with whom
you’ll want to spend the rest of your life.

What's Your True Age? (Back to Top)
According to aging experts, you are, in many ways, as
young as the health of your habits. RealAge is a system
of measuring your biological age (as opposed to your
calendar one) based on 137 factors that can influence
your rate of aging. To begin to get an idea of what age
you look, feel and function at, answer the following
questions (the full assessment is available free at
www.realage.com):
DO YOU GET YOUR VITAMINS? Regularly taking
supplements of vitamin C (1,200 mg/day), vitamin E
(400 IU/day), calcium (1,000–1,200 mg/day), vitamin
D (400–600 IU/day), folate (400 mcg/day), and vitamin
B6 (6 mg/day) can cut six years from your RealAge.
Check your multivitamin to see how it compares.
DO YOU HAVE A HANDLE ON STRESS? Periods of
intense stress can add as much as 32 years to your
RealAge. But maintaining good stress-reduction strate-
gies and strong social support networks wins back as
many as 30.
DO YOU SMOKE? Smoking adds eight extra candles
to your RealAge. The good news? Quitting will knock
seven right off.
DO YOU LISTEN TO YOUR DENTIST? Daily flossing
and brushing cuts 6.4 years from your RealAge. Left
unchecked, the plaque on your teeth is the same bacteria
that leads to inflammation and clogging of the arteries,
while periodontal disease and tooth loss puts your
immune system at risk.
ARE YOU ACTIVE? Even a small amount of exercise —
as little as two 20-minute walks a day — can shave five
years off your RealAge.
DO YOU GET YOUR FIBER? Getting at least 25 grams
offiber a day can make your RealAge 2.5 years younger.
(Andrew Weil, MD, recommends as much as 40 grams.)
DO YOU LAUGH? It’s no joke — laughing a lot
reduces stress, strengthens the immune system and can
deduct as many as eight years from your RealAge.
DO YOU LOVE TO LEARN? Becoming a lifelong
learner can reduce your RealAge as much as 2.5 years.
ARE YOU CURRENT ON YOUR CHECKUPS?
Seeking quality medical care and managing chronic
conditions wins you back 12 RealAge years.
DO YOU BUCKLE UP? Wearing your seat belt and
staying within 5 mph of the speed limit can make your
RealAge as much as 3.4 years younger.
What's Your Body Age? (Back to Top)
Many health clubs offer members free or low-cost BodyAge assessments in order to help them establish a baseline measurement of several key health and fitness indicators. The assessment provides you with your current BodyAge score, as well as a recommended fitness program.
