Three Lord of the Rings notes and queries: Frodo's coma, Frodo's overseas destination, and another possible source of the elvish strain in Men

I have done three short posts on possible 'anomalies' in The Lord of the Rings at The Notion Club Papers blog - all of which invite speculative responses. 

One is about Frodo and Sam enjoying an unfeasibly-long sleep after destroying the ring, another about the destination of Frodo and Bilbo from the Grey Havens; and another about the fate of Elrond's sons.
