Amen, Bill !!

Go with integrity. After all, WE didn't say it, we were brainwashed by

somebody in our training. But we know now that it's a fraud to extract vast

funds from the gullible body politic.

Apoptosis!  Go extinct for the good of the organism.  Like the webbing

between your fetal fingers. Or the tadpole's tail. Or the tumor following

LDR-stimulation therapy!!  :-)  (After all, we're not just stealing $100s

Billions from the public, we're robbing them of the therapies that LDR

provides.)
