As long as we continue to not drop dead from the use of cellphones in our daily lives, the move away from landlines seems totally inevitable for obvious reasons: convenience, portability, having a single point of contact, the list goes on. The Center for Disease Control's National Health Interview Survey validates that Americans feel the same way, showing an upward tick in the number of homes that have gone exclusively mobile (a weird survey to be fleshing out such fascinating stats on the wireless industry, but whatevs). Overall, 13.9 percent said they've ditched the landlines, but the real story seems to be in the breakdowns; 28 percent of renters were mobile-only compared to just 6.7 percent of homeowners. The 25 to 29 year old age bracket was the most likely to rely solely on their cellphones, with 18 to 24 coming in second -- probably because they're still living under their old-skool parents' roofs, we'd imagine. Homes under the poverty level were also more likely to go strictly with their mobiles, and finally -- here's the CDC's health tie-in -- mobile folks were far more likely to be binge drinkers, smokers, and lack health insurance, though they were also more likely to work out in their spare hours. Now if you'll excuse us, we've gotta go hit the treadmill.
