The Vegan Thread

It had me to thinking, though, about other foods that were vegan friendly. For example, can vegans eat bacterial mats or biofilms? What about placenta(s/e) (either their own, or that of friends). Their own nails? Or, as I sit here excavating my right nostril - bogies?

Bacterial mats - Why would I want to?
Biofilms - As above
Placenta - Nothing died, I can see no ethical reason preventing the consumption of Placentae
Nails - Nothing died.
Boogers - Nothing died.

You appear to be confused as to what constitues being vegan.
