Re: cadmium

Cadmium is poisinous.  It's why NiCad(NIckel-CADmium) batteries should
_always_ be recycled, and why all computers, appliances, etc. with NiCad
batteries have little stickers on them now that say "This product may
contain Nickel Cadmium batteries, which must be recycled blah blah blah..."

Wearing a dust mask is always a good idea when sanding something...even
iron in your lungs isn't great for you(iron is actually poisinous after a
certain limit in the human body; that's why you can't just pop another
multivitamin, among other things; the extra iron would be bad for you.)
