Aside from falling off the side of a mountain, drowning during a triathlon or simply slumping over my desk after suffering a rogue heart attack, I think I know how I'll die. I'll be busy texting as I stride along one of Manhattan's side streets when, boom, I'll tumble head over heels into one of those sidewalk cellar doors that seem to always be in the fixed, upright and open position. That's where they'll find my body buried in produce, neck badly broken, hand still clutching the damn Blackberry.

I've already had a few close calls. That's why I'm thrilled to see there's a new iPhone application called Type n Walk. It was literally designed to save my life, since It provides a texting walker a view of what lies ahead.

Susan Dominus, a New York Times columnist, likens texting while walking to texting while driving. I disagree. It's one thing to be distracted while driving a 2,000 pound car at 65 mph. It's quite another to be walking slowly while texting. I'll admit the latter isn't smart or particularly healthy, but it's not necessarily jeopardizing other people's lives.

I can't wait to download the Type n Walk. I just hope it’s sensitive enough to pick up those damn, dark cellar doors. I'm worried they may one day become the iceberg to my RMS Titanic.
