A U.K. researcher confirms what many dog lovers already know -- dogs are good for your health.

Apparently, dog owners are generally healthier than non-pet-owners. They have lower blood pressure and cholesterol, suffer fewer minor ailments, and stray from serious medical problems too. Dogs can prevent their owners from getting sick, help them recover more quickly when they do fall ill, and they can even warn of cancer, heart attack, epileptic seizures, and hypoglycemia, says Dr. Deborah Wells from the Canine Behaviour Centre of Queens University in Northern Ireland.

Wells, whose study is published in the British Journal of Health Psychology, says dogs buffer us from stress -- a well-known cause of illness -- and promote general well-being. Owning a dog leads to increased physical activity and increases development of social interactions -- both of which minimize stress and contribute to human health.

While Wells found those who own both dogs and cats benefit from their pets, dog owners enjoy improved health for much longer than cat owners.

In the United States, mammograms are not recommended for women under the age of 40. Other then an annual check-up and a monthly self breast exam, young women with no family history of breast cancer have no medical tools available for preventing and detecting the disease. But no woman is immune to this disease -- and being female is the single most important risk factor for diagnosis. And young women do get breast cancer. I did. And so did Sharon Rutherford, a 36-year-old Ulster woman who was diagnosed in December.

Rutherford is urging health officials to lower the age for screening in Northern Ireland -- where routine breast screening programs are reserved for women between the ages of 50 and 64. Rutherford says this is inadequate as there is an "absolutely chronic" number of younger women suffering from breast cancer.

Although there is a reduced-age screening program that monitors women beginning at age 40, Rutherford would like to see the screening age reduced to 30. Until then, she is educating women about how they can be vigilant about their own care. She urges women to report to doctors anything that just doesn't feel right. And because doctors may excuse symptoms because women are "too young" for breast cancer -- that's what doctors told her -- women must aggressively pursue medical care. Rutherford kept pursuing the thickening she felt in her breast -- and eventually she was referred for screening.

Rutherford has had a partial mastectomy, chemotherapy, and radiation treatment. And she is now active in the Ulster Cancer Foundation's new support group -- specifically for women under the age of 40.

Recently, International Agency for Research on Cancer researchers concluded a study which stated that 3.6 percent of all cancer cases worldwide are related to alcohol drinking. Today, the Centre of Public Health at Liverpool John Moores University published a report that alcoholism and binge drinking in the northern Britain cities of Newcastle-upon-Tyne, Liverpool and Durham will shorten the lives of men and women who live there and create years of health-related illnesses.

The blame for the drinking problems focuses on the government's allowance of 24-hour drinking, inexpensive booze, a night-time economy of bars and clubs and a failure to educate the public on the dangers of excessive drinking, binge drinking and alcoholism. This report, along with political conservatives, are making a public statement against what they call irresponsible actions on the part of the British government that would create an environment that promotes excess drinking, binge drinking and alcoholism.

The report indicated almost three in ten people admit binge drinking. According to director of the Centre for Public Health Professor Mark Bellis, "We hope that making these statistics widely available will highlight that we are no longer a nation enjoying a harmless tipple but increasingly one developing a dangerous alcohol addiction."
