The really appalling thing is that you yourself contain a hundred thousand billion cytoplasts (and that's not counting the cytoplasts of all the bacteria who call you home - there are a thousand thousand billion of them).
The really really appalling thing, of course, is that I contain just as many cytoplastic bits, myself.

Word Not To Use Today: cytoplastic. The cyto bit comes from the Greek kutos, vessel or container, and the plastic bit comes from the Greek plassein, to form.
