Testing.

I have for many years been an advocate of not using chemicals around the house wherever possible, especially where children are concerned. Yet people will spray 'room deodorizers' into the air instead of opening windows. They will spray a biological poison to kill a fly or bug near their child. They will microwave food on plastic not meant for the microwave.
It is not just these unthinking acts; it is the fire retardants and preservatives used in so many products that give rise to long lasting medical conditions. Then the child is 'treated' with drugs from pharmaceutical companies that couldn't care less about the child.
We all need to start thinking from the beginning again.
