Personally blicero, I think everyone in the modern world needs to chelate.

So you like to suck tailpipes too huh? I left NYC in 1990 with bleeding lungs from doing that (I would ride my bike in traffic, across the Brooklyn Bridge and through lower Manhattan was my favorite ride), among other not very good for you stuff, work related. Do you get the black stuff in your nose and black soot streaks on your face too?

The lungs healed up within a couple months in Florida, the air was cleaner down there then maybe, no problems like that since. However from my recent blood tests of just 5 months ago it is quite apparent that my high lead levels came from somewhere. I am certain it was my time in NYC, I did live there for a dozen years and worked with numerous chemicals/paints/pigments/resins.

My doctor said anything showing in my blood tests could be as old as I was. Which leads me back to the conclusion that everyone should chelate, some more than others.
