Do you know any interesting or unusual facts regarding vegetarian/veganism?

[dnahabitue]

I just read that "Vegetarians are less likely to die by choking on food since the most common food to obstruct the airway is fish, which caused about 4,500 accidents a year in the UK as of 1998. Meat, poultry and bones were cited as the next three most common causes of choking."

There's one argument for veganism I thought I'd never hear.
What obscure and/or irrelevant facts do you know about veg*nism? Please source!
