Thank you Pete and thank you Alfredo, and apologies to Stoned for sounding snitty. Text is often emotionless and I missed the joke.

I can't tell whether you are serious or joking. I sincerely hope the latter. Again, where's the health hazard? It's a cobble that stinks like sulfur ...

Nice write-up on why we shouldn't eat our specimens, crush them and snort the powder, or rub them vigorously on skin (especially injured or broken skin)...with that I'm stepping off my eternal soapbox ...

Hi again Roger,

humans form bezoars too...but not ones made of apatite. :)

Hi Casimir. Catching up on things, I see that my thought was already expressed by Alfredo and Peter in an earlier post of yours. No need to pick it up again (and nice to know I'm in good company). ...

And Tracy is truly an expert in this field.

Thanks Les for the endorsement...I have to check out the commercial to which you refer. It sounds quite appropriate!

I'm not climbing back on my soapbox. :)
