Health care is expensive, even for those with insurance. My treatment with the breast cancer drug Herceptin cost $5,000 every three weeks for 52 weeks. Insurance paid 80 percent; I was responsible for 20. That's $1,000 every three weeks. Not exactly affordable.

What many of us don't know is that we can play an active role in cutting our health care bills. We can shop around for everything, for example. Before filling a prescription, consider comparing prices offered at mail-order and online pharmacies with those of larger retailers. You may even find that mom and pop shops offer competitive rates since they can set their own pricing. Don't forget about generic drugs too. Ask your doctor if a generic version of your medication is just as good as a brand name drug. If so, go for the price break.

Did you know that lab work is more expensive if you get it at a hospital? Ask your doctor for other trustworthy locations and save a few bucks.

As Larry Stewart tells it, the story begins 26 years ago, when a week before Christmas he was fired from his job. It was the second year in a row he had been fired from a job the week before Christmas. As he sat in his car at a drive-in restaurant commiserating his untimely employment fate, he noticed the car hop was not wearing a warm coat as she worked in the elements of winter cold for nickels and dimes in tips. Although his recent unemployment status made his financial security uncertain, he decided to pay for his meal with a $20 dollar bill and told her to keep the change.

What happened next changed his life and the lives of countless others who would come to benefit from the generosity of a stranger. The car hop began to cry. She told Stewart he had no idea how much the extra money would help. Touched by her reaction, he went to the bank, withdrew $200 dollars, and then drove around looking for people who might need a few extra dollars.

Over the last 26 years, the cable television and long-distance telephone service businessman, who went on to earn millions after his rocky start in the working world, has given away over a million dollars. Anonymously. Stewart never wanted anyone to know his name or the name of his company. Until now.

Stewart has been diagnosed with cancer of the esophagus that has spread to his liver. He thinks it is time to reveal the mysterious identity of the Secret Santa many in Missouri and elsewhere have wondered about for the last 26 years. Why? By speaking publicly about giving, he is hoping to inspire others to give. According to Stewart, "that's what we are here for -- to help other people out."

I've written twice before about a young woman named Diem Brown. I first wrote in August about her appearance as a contestant on MTV's Real World/Road Rules Challenge reality show. I wrote about how despite a recent diagnosis of ovarian cancer, she took herself to Australia to compete in physical and mental challenges with other spunky 20-something competitors. Brown, 25, fought for a cash prize of $250,000 -- while fighting cancer at the same time.

Brown did not win the grand prize, but she did win the admiration and respect of her castmates who on an MTV reunion show applauded her tireless and heroic efforts. In my second post, in September, I wrote about Brown's presence on the reunion show, about her strength, about the great mindset she acquired prior to returning home from Australia for treatment. I wrote about her foundation -- Live for the Challenge -- a wedding-type registry that allows patients to register for prescriptions, wigs, anything that helps them manage their illnesses. I did not write about the wig Brown wore on the show -- but it was apparent she had lost her long, blond hair and was masking the most visible side effect of chemotherapy.

Brown reluctantly yet powerfully unveiled her head on national television just a few nights ago during the beginning of another MTV Real World/Road Rules Challenge. During this installment -- The Duel -- Brown competes again, this time with the shortest of brown hair covering her scalp and with a fierceness that rivals anything she's offered on past shows.

Brown is back. She's in Brazil. And she is beating cancer.
