Teflon can make you terminally sick: the Teflon-sprayed bullets were
used by hitmen to pierce the Kevlar body armor more efficiently. I bet
that the those fine Teflon particles imbedded together with your bains
all over the wall must be unhealthy.

Now, seriously - if you are a smoker, avoid getting a fluorinated lab
grease Krytox on your fingers. I heard that the teflon flu actualy
works quite nicely if you happen to contaminate your cigarets with the
stuff and it gets pyrolysed as you smoke it. In case that your boss is
a smoker, it was not me who gave you the idea.
