Just how addicted are we to Cell Phones?

A survey of 3,000 cell phone users by BBDO reveals just how freakishly hooked folks are to their cells. The survey of 3,000 cell phone users, ages 15 to 35, in 15 countries found these nuggets - some predictable, others disturbing:

• 81% of 15- to 20-year-olds sleep with their phone on.

• Percentage of Americans who said a cell phone reflects as much about someone as a car does (70% of Chinese agreed): 31%

• 26% of Americans said they'd go back for their cell phone over their wallet if they left both at home (69% of Chinese agreed).

• 63% of Americans wouldn't lend their cell phone to someone else (90% of Japanese agreed).

• Percentage of cell-phone users who screen their calls: 96%

• 44 percent of Americans have found ways to flirt using their cell phone, such as through text messages.

• 14 percent of the world's cell phone users report that they have stopped in the middle of a sex act to answer a ringing wireless device (22% Germany, 15% in the US).

And from the McGyver files, our cellphones can come in handy in a pinch. A survey from Sprint found almost 2 of every 3 people used their cell phone backlight to look for something in the dark, mostly keyholes and walkways, while 7 percent said they used their backlights to cheer on their favorite band at a concert, replacing the trusty lighter of the past. And finally, 4 percent have used it to light up their face to tell a ghost story.
