Cellphones are great in case of emergencies, keeping in contact with friends and family. Cellphones can also be a nuisance... they can be very distracting to those around us, they can cause us to be interrupted at inappropriate times. Cellphones can also be very distracting while driving, by causing us to loose our focus and can even result in an accident. In the last 5 years or so experts
