"The idea that 'one fibre will kill' is not supported by scientific evidenc=

We all have far more than one fiber of asbestos sitting in our lungs right =

[ This is starting to veer off-topic. We can agree that many
materials in electronics and speakers can be hazardous and
warrant appropriate caution. Discussion of such is on-topic,
but should be related back to audio. --dsr ]
