I heard today on the radio that there's a shortage of blood supply here in Gainesville, Florida. Reserves are so low there's barely enough blood to last one full day at a time. LifeSouth Community Blood Centers reports about this emergency blood shortage on their website.

"The blood supply stands at less than a one-day supply which has blood center officials very concerned," writes John David Larkin Nolen, LifeSouth's Medical Director. "All eligible residents are asked to give blood. Blood donations haven't kept pace with demand and we've had a very tight supply for the past few weeks. But today several patient situations involving children and adults facing life threatening medical conditions depleted the reserve supplies. We're worried about our overall ability to make sure the patients that need blood will receive what they need during the next few days."

I wish I could donate my blood, but I can't. Until I've been free from cancer treatment for five years, no none wants it. But maybe you can help. Try tracking down your local blood center and see what you can do to help. It may just be the gift that saves a life.

My gut hasn't always guided me through life's most difficult decisions and dilemmas. It wasn't until I felt a lump in my breast more than two years ago that my gut kicked into gear and told me something very important.

"It's cancer," my insides told me one week before the surgeon who did my biopsy called.

"It's cancer," the surgeon said. I didn't tell him, but I thought it: "I know."

I also knew prior to surgery that my cancer had not spread to my lymph nodes. My gut told me this too. It also told me the chemotherapy drug Taxol was not right for me -- since my cancer had not spread -- despite the urging of one oncologist that I accept this treatment. I would have gone on gut instinct alone in my rejection of this medication but another doctor weighed in and agreed with my gut, so I had solid backing on this decision.

Many have dismissed hunches like these and have written off those who believe in them as screwballs, says writer Chip Brown in the March 2007 issue of The Oprah Magazine. But as Brown shares after peering into the world of gut instinct, there are 100 million nerve cells in the gut. They run on autopilot, regulate digestion, play a critical role in the body's immune system, and control mood-altering neurotransmitters identical to those in the brain.

The gut is essentially a second brain. It was a "gut feeling" that led Fred Smith, founder of Federal Express, to begin exploring the possibilities of overnight delivery and Howard Schultz, founder of Starbucks, to begin mass marketing coffee. Wall Street professionals make millions on their gut feelings, sportscasters make startling predictions based on gut guidance, and entrepreneurs launch thriving businesses because of the inklings that rumble in their tummies.

You may or may not be a gut thinker yourself. But I've stumbled upon a gut exercise -- thanks to psychotherapist Nancy Napier --and I'd like for you to consider it the next time you find yourself stuck at a crossroads, unsure of where to turn. You never know, the direction you seek may be swirling around in your midsection, just waiting for a call to action.

Think about this:

You are wavering between two choices. Find yourself a quiet, serene place where there will be no disruptions. Now sit down. Take a moment to settle and focus on the issue you want to explore. Then choose one side. Think about this side and notice what happens in your gut. Do you feel a tightening and gripping or a softening and warming? Are the sensations pleasant or uncomfortable? Notice your thoughts. Are they positive or negative? Give yourself some time to feel your gut and your mind responding.

Now shift to the other side. Think about the previous questions, and try to chart what your body gut is saying.

While you may not get a gut answer at first, if you come back with the question several times, you'll likely hear just what your gut wants you to know.

Baltimore region's blood supply hit an annual low. Blood donations are typically slow in January but the need picks up with surgeries back on schedule after the holidays. Types O and B seem to be particularly low.

Baltimore Health Commissioner Dr. Joshua Sharfstein called blood donation "a very thin red line that connects a lot of people in the community". He also stated that as a physician, it is a very horrible moment when you think that blood may not be available.

Blood can not be manufactured in a lab, it has to be given by people. Premature babies require blood donations in order to live, trauma victims need blood so they don't die, cancer victims require blood sometimes because of very toxic therapies, and that is only a few of the reasons blood is so desperately needed.

M.D. Anderson Cancer Center says that patients require approximately 100 units of red blood cells and 400 units of platelets everyday. The M.D. Anderson Blood Bank is a leader in the field of transfusion medicine.

Giving blood provides hope to cancer patients. To donate blood for transfusion for another person, you must be healthy, be at least 17 year's old, weigh at least 110 pounds, and not have donated blood in the last 8 weeks.

Cancer survivors that would like to donate can if their cancer has been treated successfully and it has been at least five years since treatment was completed and there has been no cancer recurrence. Some low-risk cancers including squamous or basal cell cancers of the skin do not require a five year waiting period. If you have had leukemia or lymphoma including Hodgkin's disease, you are not eligible to donate. Go to eligibility criteria to find out more. You can also visit the Red Cross.

My brother-in-law came up to me tonight with his iPod and handed me his headsets. A cue to put them on, I guessed -- and so I did. A song played and right away I liked what I heard. It was the exact type of music I like -- with a grungy, rock kind of sound. I figured Jack knows what I like and was sharing a new song with me. Which he was -- but there was something more to it. It wasn't just a good song -- it was a good song about cancer, with a message of hope and strength and living through the struggles of a life that has been shaken. Written by Scott Leger of the Austin-based band wideawake, Maybe Tonight, Maybe Tomorrow is dedicated to the millions of people affected by cancer -- those who have lost, those who have survived, those who fight and volunteer and support and research and raise awareness and give and inspire. And for those without cancer too really. For anyone who is faced with forces that threaten the most precious of assets -- time.

Traditionally, the medical community has focused its resources on cancer treatment in saving lives. Rather recently, there is a growing trend and interest in cancer prevention. As a result, there is more awareness and conversation about the causes of cancer, and the ways to prevent cancer. Although less than ten percent of the population links cancer risks to obesity, one of the leading lifestyle factors that is known to raise the risk for cancer is obesity. The Rudd Center for Food Policy and Obesity at Yale University conducted an online survey that revealed rather startling results. When it comes to obesity, half of the people who responded to the survey said they would give up a year of life rather than be obese. In addition, they indicated they would walk away from their marriage, give up the possibility of having children, be depressed or become alcoholic rather than be obese.

It gets more extreme. Five percent said they'd rather lose a limb than get fat, while four percent said they'd rather be blind than be overweight. Of those who responded, three percent were underweight, 41 percent were normal weight, 21 percent were overweight, 21 percent were obese and 14 percent were very obese. There is something desperately sad about the truth of how we feel about being fat. Being overweight is not good. Maintaining a healthy weight is good. However, it seems being fat is dangerously weighted in more than our concern for health. The psychological pain appears profound for many even considering the possibility of being overweight and illustrates the lengths people would be willing to go to be thin. Alcoholism? Loss of limb? Blindness?
