Asbestos was the best crap that ever came out of the ground,,, but like everything good, it's very bad for you.
I was certified and used to do survey's for asbestos abatement when the clean up bug hit and while getting certified was told one thimble full thrown in a gym could possibly kill you. in most cases it doesn't show up for 20+ years until your body rejects it. It is a terrible why to go.
most schools. buildings, ships, cars, and homes where full of it up until the late 70's. if you have an old house you probably have it somewhere (like pipes, furnace, popcorn ceilings) so don't disturb it!
The stuff killed everyone in the places where it was mined and the workers took it home and killed the family too , it's killed many a sailor and plumber so it's serous stuff. :doah:
