Billie Iverson may be getting up there, but for an 86-year-old, she's still plenty active.

"I take trips, and I go do my own shopping, and I take myself to the doctor," Iverson says. "I do everything. I don't let anything stop me."

But one day, she got hit with something she'd never experienced — the worst case of the runs ever.

For days at a time, off and on for weeks, the problem kept coming back. Iverson eventually got so weak, she ended up in a nursing home.

"I just thought maybe I wasn't going to make it," she says. "I thought I was going to die."

Look in the mirror and you won't see your microbiome. But it's there with you from the day you are born. Over time, those bacteria, viruses and fungi multiply until they outnumber your own cells 10 to 1.

As babies, the microbes may teach our immune systems how to fight off bad bugs that make us sick and ignore things that aren't a threat.

We get our first dose of microbes from our mothers, both in the birth canal and in breast milk. Family members tend to have similar microbiomes.

The percentage of middle and high school students who have tried electronic cigarettes more than doubled in a year, federal health officials reported Thursday.

Those who reported currently using the devices increased from 1.1 percent to 2.1 percent.

Scientists have discovered new clues about how microbes in our digestive systems may affect health.

European researchers found that the less diverse those microbes are, the more likely people are to gain weight, become obese and develop risk factors for serious health problems.

Evidence has been mounting in recent years that bacteria and other organisms in our bodies do a lot more than just help us digest food.
