Every day there is a new study about something that will kill us. Yesterday it was countertops, and today it was cell phones (again). According to a prominent professor at the University of Pittsburgh, cell phone use can cause brain tumors- especially in young and developing brains. It helps if you don't put the phone near your head, but use a headset or speaker phone instead.
In the movie, "Waitress," Joe says "life will kill you." I guess that's true, whether or not you use a cell phone.
It's funny though, the messages and warnings people choose to heed- someone might avoid artificial sweeteners but not wear a seat belt. Others might not choose not to fly in airplanes, but smoke a pack a day. We are not rational beings, that is for sure.
Personally, I think I'll use my headset a little more often, and reduce my use of plastic food containers, but I'll still go to Arby's for a beef and cheddar sandwich and curly fries every now and then!
