A couple years ago I traded in my cell phone for an internet connection, and I have not regretted that exchange. Part of the reason the cell phone drove me crazy was that I was too easy to reach for my coworkers, essentially putting me "on call" all the time. The other reason is that I started reading about the radiation of the cell phone signal rearranging molecules in our brains, and possibly causing brain cancer. Well here's a new study that makes me worry about my friends who still mainly use a mobile phone. Please minimize your cell phone use! If the side of your head starts to feel warm, it's past time to hang up.
