I recall one of those "consumer" TV shows a year or two ago which looked into the subject of EM fields and health.

It wasn't a serious scientific discussion, but one thing which has stuck in my mind is the home where they found a very high gauss level around the head of a bed in one of the children's rooms. The service entrance and meter were located on the other side of the partition.

I've been surrounded by electromagnetic fields of various types in my work for over 20 years, and before that through many childhood years of "playing" with radio and electronics. I guess I've never really stopped to think about possible side-effects.
