Obesity is contagious

This is one study that will come as no shock to anyone who's tried to stay on a diet while hanging out with sugar-loving friends. They have found that having obese friends is likely to lead you into obesity as well.

The more obese friends you have, the more likely you are to become obese, a new study suggests. This confirms previous research that gaining weight may be socially contagious...

"We find that having four obese friends doubled people's chance of becoming obese compared to people with no obese friends," says Alison Hill, the study's lead author and a Harvard researcher.

About the rising incidence of obesity, she says, people have gotten better at gaining weight in recent years, but not at losing it.

David Rand, a Harvard research scientist who also worked on the study, says that the more obese people you have contact with, the more likely you are to become obese.

From my experience, the opposite is true as well - have a few friends working to lose weight or maintain their weight-loss makes you much more likely to be losing weight. Why? Simple - it's easier to exercise together, just as it's easier to pig out together. Whatever you make the center of your social calendar becomes central when you're craving human contact.

H1N1 (Swine) Flu may present without a fever

I have been critical of the panicky tone that mainstream media stories about H1N1 (i.e. Swine) Flu have taken on. During slow news times, it has been the default story with the clear undertone - "We're all gonna die!"

But the H1N1 truly is a weird mutation of the virus, and it is preventing doctors from always getting a tight grip on what they are fighting. The newest wrinkle is H1N1 infection may NOT spike a fever in some patients. Fever is used almost universally as the sign of a serious flu, and the lack of this in many Mexican patients may indicate that American flu counts may be low. The virus is also presenting with diarrhea, which is not typical of most influenza infections.

The moral of the story? If you feel sick, and there is no clear cause like allergies or that week-old slice of moldy pizza you ate last night, go to the doctor for diagnosis. Properly treated, H1N1 is easily cured. Left untreated, it can be deadly... and highly infectious.
