You've surely known kids whose parents smoke declare their repulsion for the habit. The health risk, the expense, the filth of smoking seem to deter many youngsters from following in the footsteps of mom and dad. Theoretically, anyway. In practice, these same kids may fall prey to the very act they vowed to reject.

How about kids raised in households filled with sugary snacks and drinks, foods packed with fat, salt, and calories, and parents with expanding waistlines? Seems only natural these children, despite good intentions, end up struggling with healthful eating and weight management.

We are what our parents teach us. It's all we know for a good many years. And by the time we are able to make our own independent decisions, it's often too late. Our parents' actions and values are already programmed within us -- and it takes hard work to switch things up.

So here's my plea for this Sunday morning: do your kids a favor and become a positive role model. Don 't just tell your little ones what is right and healthy and virtuous -- show them. Let your behavior be the gold standard now, so that later, it's likely to be what your sweet babies will fall back on.

Here are seven ways to get started:

Feed 'em well
If kids learn healthy eating habits early, they're likely to stick with them. Offer whole grains options (rice, bread, pasta) and snacks that are not in the junk food group. Don't even buy the stuff you may later wish to clear out of your cupboard. Guests at our house are offered two drink options -- water or milk. Why? Because if we have juice (it's loaded with sugar) or soda (also sugary and calorie-laden), our kids just can't hold back. But if we don't have these beverages, they are never an option. Out of sight, out of mind.

Keep 'em moving
Take your kids to the park, get them running around your backyard, take them swimming, organize a kid-friendly football game, invest in a kite. Quiet activities are also good -- and necessary -- but when in doubt about how to entertain your busy little bees, make them move!

Let 'em see you sweat
You need to keep moving too. Not only for your own well-being -- that's obvious -- but so your kids see your physical activity as a staple of healthy living. Teach your kids to do push-ups and sit-ups and do them together. Jump rope, run laps at a local track, ride bikes, or dance. Just don't expect your kids to stay active if your idea of exercise is flipping through TV channels.

No TV
Turn off that TV. Rid your household of junk-food commercials, mind-numbing content, and addictive inactivity. Let TV be a treat -- a small one -- and not an expectation.

No smoking
Need I explain? It's unhealthy, costly, dirty, and a sure contributor to cancer. Try with every ounce of your being to keep this habit away from your impressionable children.

No stress
Some stress is unavoidable. Some is even healthy. But the kind of stress that hurts our tummies, gives us headaches, and threatens our health should be minimized. We must do our best to control our own stress so its effects don't spill over. And we must teach our kids how to cope too. Fortunately, some of the techniques listed above also work for this category -- physical activity, for example, does wonders for lowering stress. We can become experts at deep breathing -- have your kids practice with you. And we can teach a bit of distraction. If homework is making kids crazy, go with them on a short walk where they can regroup and return to the task with a clear head.

No double standards
We simply cannot say one thing and do another. Smoking while preaching the dangers of the habit just doesn't make sense. Saying "no" to sweets with your hand in the cookie jar is downright unfair. Carrying around extra weight and demanding physical fitness is simply ineffective. So make a commitment to yourself and your kids that you will do as you say. It's the only way.

Photographs tell powerful stories. They depict people and objects and landscapes and emotions in deep, meaningful ways. They capture permanent visual representations of moments in life. They paint pictures that even the most well-crafted words could not reproduce.

When Mary Ann Nilan was diagnosed with breast cancer in 2004 at the age of 40, she knew her story must be told -- through pictures. So she asked a photographer to record it all, stating, "I hope the pictures make the road easier for other women." The rest is history.

She calls it a photo essay and titles it The Diary of Healing. For 17 frames -- with photographs dominating each space and text kept to a minimum -- Nilan shares her journey that began with the discovery of breast cancer in both breasts and several lymph nodes, the journey that took her through chemotherapy, a double mastectomy, and reconstruction with implants.

Her photographs document significant stops on her physical and emotional trek. They show her bald head, the wig she wore only once and then let hang on a hook, the scars that crossed her flat chest after surgery, an injection of saline that painfully pierced the skin of her new breasts, her children measuring her hair as it grows in after chemotherapy. The photographs are both hopeful and chilling. They are breast cancer. They are more than words could ever capture.

When I was first diagnosed with breast cancer almost two years ago, my greatest fear was losing my hair. The fear was consuming, painful, over-the-top. That was long ago -- and I survived. I can look back now and realize that the panic about losing my hair was such a small-scale fear -- compared to what I fear now. Now I fear a recurrence of cancer. And it's a whole lot more disabling than a little worry about being bald.

I have a few techniques for settling my fears when they get out of control. Sometimes I take deep breaths. Sometimes I distract myself and occupy my mind with something more pleasant than anxiety -- like writing, exercising, playing with my little boys. And sometimes I read about others who have come before me and have handled the same distress I sometimes feel about cancer taking up residence in my body again. Mostly I learn from stories of other women who have survived breast cancer. And I learn that I can handle the fear, that I can handle cancer if it does come back. And the women I find most inspiring are those who have had a recurrence -- or two or three -- and who still manage to happily tackle the life they have in front of them. They give me hope that if a recurrence comes my way, I too can conquer it. And here are seven snippets of hope from the book Hope Lives! The After Breast Cancer Treatment Survival Handbook -- from women who keep on surviving breast cancer.

University of Texas M. D. Anderson Cancer Center researchers have confirmed what more than a few cancer patients have personally believed for some time now. Stress increases cancer growth and finding ways to relax and reduce stress is beneficial to cancer survivorship.

In a preclinical study carried out on mice with ovarian cancer, researchers found that cancerous tumors grew and spread faster when the mice were experiencing increased levels of stress. According to the researchers, the conclusion of this study is the first definitive link between psychological stress and the biological processes that make ovarian tumors grow and spread. It appears stress hormones bind to receptors directly on tumor cells and, in turn, stimulate new blood vessel growth and other factors that lead to faster and more aggressive tumors.

"The concept of stress hormone receptors directly driving cancer growth is very new," said Dr. Anil Sood, the study's senior author. "Not much had been known about how often these receptors are expressed in cancer, and more importantly, whether they had any functional significance. Our research opens a new area of investigation."

The good news in this -- besides the fact that this study begins to validate what cancer survivors have been saying for years in the personal belief of the link between stress and cancer -- is that stress can be controlled and reduced by lifestyle changes and medication. In fact, the researchers found a beta blocker heart medication effectively blocked the adverse effect stress hormones had on tumor growth.

This could open new areas of research. Indeed, Dr. Sood and his team will continue to research the role of stress in cancer and examine the effects of stress hormones on cancers besides ovarian cancer.

Drugs appear to be quite a slippery slope for bodybuilders, taking a second drug to offset the unwanted side effects of the first drug. According to University of Glamorgan researchers, 22 percent of bodybuilders use Tamoxifen because steroid use causes breast growth.

Tamoxifen has a few potentially serious life-threatening side-effects such as deep vein blood clotting and the increased risk for the development of new tumors.

Women breast cancer survivors often struggle over whether the benefit of taking Tamoxifen overweigh the risks. In the case of breast cancer prevention, most women go ahead and take the drug, but not without hesitation. That anyone would chose to take such a powerful drug without an absolute need is beyond logic and reason. My suggestion? Stop using steroids. Don't take the first drug -- won't need the second one.

The body speaks in visual clues revealing the state of our health. For example, a trained practitioner can tell you if you have heart disease by examining how your fingernails grow. Deciphering what the body is trying to say is a continuing learning process for the health community. Now, there might be one more clue that is understood.

According to researchers, deep facial wrinkles indicate lung weakness and a sign of lung disease. In a study done at the Royal Devon & Exeter National Health Service in Britain, the participants who had significant wrinkles of the face were five times more likely to have COPD and three times more likely to have severe emphysema. It has been well-established that some, but not all smokers, develop decreased lung function and eventual COPD. Researchers believe the results of this study will alert physicians to the potential for lung disease when treating patients who show extensive or deep wrinkling of the face.

I have had many moments in my life where anxiety and panic have filled my mind. But this is normal and necessary really as life delivers all kinds of situations that produce all sorts of emotions.

I can recall vividly anxious feelings before a school exam but this is what motivated me to study and prepare and to pass the exam with flying colors. This anxiety gave me a push, a kick in the pants -- in a good, healthy way.

Without a bit of panic, I may not have cared. I may have been aloof to the importance of doing well in school. But while life has presented me with a good amount of this healthy emotion, it has also tossed an abundance of unhealthy anxiety and panic my way -- the kind that has consumed my mind and twisted my insides. The kind that made peaceful living seem impossible.
