News: More on Cellphone Dangers

 Here’s more on the dangers of cellphones: the BBC reports that people who chat on their mobile phone while walking could be hurting their back, according to scientists at Australia’s University of Queensland.
They say the human body is designed to exhale when our feet touch the ground. This helps to protect the spine from sudden jolts. However, talking and walking at the same time disrupts this breathing pattern, leaving the spine exposed.
Of course, this has implications beyond cellphones. Seems that a lot of us walk and talk at the same time, with the possible exception of Gerald Ford.
