Asbestos

I do not care if others 'yawn' or if it looks as if I am here to
preach however until you have lost someone to this deadly substance
and have thoroughly researched the chemistry of this lethal substance
it is an act of folly to even consider using it outside the most
stringent of laboratory conditions. A lady (one of our neighbours)
developed an incurable asbestos-related cancer after simply hugging
her father who once worked in an environment where asbestos was used

So if you choose to use it, remember it is not just yourself that you
are exposing to an unnecessary risk - but your family, your employees
and/or your customers.
