John, all

I wonder too, and I`l never know, because being a smoker, if I die from
lung cancer, nobody will want to look into the possibility of the cause
being thorium dust. (I can hear the doctors walking down the corridor

Well, I use a mask most of the time, but don`t pay much attention to it
as I probably should.

Chers, Fin Hammer
