After months of Advanced Dungeons and Dragons, I would have to say human. Elves would be my second choice, but they live too long. Being a hobbit might be all right, but I don't fancy living in a rabbit hole. Dwarves are irritable. Orcs are barbaric.
Poets can express insanity.
Scientists just start with the wild experiments and are over the deep end before anyone realizes it. Study Norse culture and set traps at the doors and windows with barbed wire and tacs. Then I'd buy a few guns to pelt the primitive dolts with and notify law enforcement. You tell me. 2.Neither - the poet is mad to start with, the scientist gets there in the end.
