Andy - when you get time.

I have a piece of pencil "lead" embedded in my hand since 1st grade,
when I stabbed myself pretty good. It's still visible under the skin,
but I tried digging once and I couldn't get it out.

Is this something to be worried about?

My hair lead level is presently mildly high (yellow), but was
exceedingly high in my infant and adolescent hair.

What is this "lead"? Is it just graphite?

Dave.
