You forgot a few:Avoid fear mongering espoused by those who profit from such.
Avoid all things that can't be proven with 100% certainty to the satisfaction of everyone.
Avoid one of the great cities of the world, San Francisco, because it has 4G cellular service.
Avoid walking by the homes of the city council members opposed to wifi because they have wifi.
Avoid sitting in front of the monitor that emits RF typing in recommendations to avoid RF on an online bulletin board.
Avoid living in the real world.
Better yet, just avoid reality altogether.
I challange others to come up with other things to avoid.
