About 25 to 30 percent of people prescribed statins dump them within a year. I flunked Lipitor after a few wretched months.

Side effects can include muscle weakness, diabetes onset and, rarely, permanent muscle damage. These risks are higher in women, with age, and with certain heart and blood pressure drugs.

The viruses that cause the common cold are always lurking. But consider this: Even if we touch a doorknob or keyboard that's covered in cold germs from an infected person, we don't always catch the cold.

"Sometimes when we're exposed to viruses, we end up not getting sick," says Aric Prather, a psychologist at the University of California, San Francisco, who studies how our behaviors can influence our health.

In less than 24 hours, Valerie Davidson has 50 people coming to her house for dinner.

She had planned to catch and cook enough salmon for the main course. But early in the morning, Alaska opened the Kuskokwim River to commercial fishing, which means subsistence fishermen like her can't fish on it.
