Data from a new study suggests that the majority of us are taking high-tech too far: We're using our smartphones in the bathroom, a lot.

A survey of 1,000 Americans completed by 11mark says that 74% of men and 76% of women have used their mobile phone in the bathroom. What are we doing in there? Well, 63% report they have answered a phone call, and 41% have initiated a phone call. (What is wrong with you people, is no place sacred?)

Two-thirds of respondents have read a text message in the loo (okay, I've done that, guilty), and 38% have surfed the Internet (I think I've done that, too.) The results suggest that men are more apt to smartphone-it while in the stall, as 30% say they won't go to the bathroom without their mobile phone. Only 20% of women fall into the same category. Men are also more apt to answer the call of duty while answering the call of nature, as 20% of respondents have taken work-related calls while in the bathroom, compared to 13% of women doing the same.

How do things break down based on device? Android smartphone users are the worst restroom offenders. According to 11mark, 87% of Android users have broached bathroom etiquette, while 84% of BlackBerry users have, and 77% of iPhone users have.

BlackBerry users answer the most business calls in the lavatory, with 75% picking up the phone. Two-thirds of Android owners and 60% of iPhone owners report answering the phone in the stall. Android and iPhone users are more apt to use social networking applications, however.

Last, the study parses the data based on age. It should be no surprise that Millennials are the heaviest IT in the toilet users. A whopping 91% use their smartphones in the bathroom (remind me never to touch a young adult's smartphone for any reason). Older users are only slightly less apt to use their phone in the bathroom, with 80% of Generation X respondents and 65% of Baby Boomers ringing up as guilty.

"The writing is on the stall," says Nicole Burdette, principal, 11mark. "This study confirms what we all know – that the last private place is no longer private."
