There's a new theory that Jane Austen died from cow TB. And you know what? That is super lame. But, on the plus side, if you become a really famous author, dear reader, in 200 years people will come up with all sorts of theories about what killed you (hopefully not something terribly ironic, like a huge paper cut at a book signing).
