If you feel like you are online constantly, you are not alone.

A new poll by the Pew Research Center finds that more than one in five Americans spend most of their free time online.

Age seems to have something to do with those numbers. Over 35 percent of people ages 18 to 29 say they are "almost constantly" connected to the Internet. But only six percent of people 65 and older reported going online that much.

Researchers say this is the first time it has included the "almost constantly" as an answer option in its survey of Internet usage.
