Three-quarters of American adults, age 18 and older, have access to the internet, a percentage which held steady throughout 2008.

83% of internet users, or 61% of U.S. adults, have looked online for information about any of the health topics we ask about, ranging from information about a specific disease, a certain treatment, alternative medicine, health insurance, doctors, hospitals, and ways to stay healthy.

BOTTOM LINE: Be careful. Consult with a health professional before you act upon any suggestions found on the internet.
