I only turn MINE on when I need to call someone in an emergency, which is extremely rare. Far too many people in this part of the world live and DIE for, and because of, their cellular telephones.

But what if someone is trying to call YOU in an emergency? You'll never know if your phone is off.
There are times I can't answer, but I always leave my cell phone on and let the voice mail relay the emergency, or my Hollywood audition results.
Cellphone Cancer? Possibly... if you hooked it up to a rat's ear 24/7 nonstop for 18 years.
