LOS ANGELES (KFWB) — Are your thumbs tired? A new study suggests if you’re over the age of 18, you may have just recently caught on to the text-messaging trend.

A new report from the Pew Research Center shows 72 percent of adult cell phone users are now sending and receiving text messages, a significant jump from 65 percent in September 2009. While the vast majority of teens are already texting — 87 percent to be exact — it’s becoming increasingly more common for their parents to be thumbing away as well.

KFWB 980′s Maggie McKay talks to Amanda Lenhart, a senior research specialist at the Pew Research Center’s Internet & American Life Project and the author the report.
