Cell phones tend to bring out the curmudgeon in me.  I consider driving an art form, and I just KNOW for a fact that one cannot drive intelligently and talk on a phone at the same time.  It doesn't matter whether a head set is being used:  the human mind cannot concentrate on two things at the same time.

Conclusion:  cell phones are dangerous to drivers.

But they are also potentially deadly if there is an electric storm in the area.  If there is lightning about, do not, I repeat DO NOT hold a cell phone to your head.

This is why.
