I have carpal tunnel so I can't write more than four hours total without tingling numbness. I take a lot of breaks and do stretches.
I don't think anyone's normal.
My family is filled with wonderful storytellers. I lack their gift of gab, so it's a relief to be able to write.
I do get flak for the lack of romance in my stories.
I don't know if I have a book in me, but I'm sure I have more essays.
I usually tame my off-kilter sense of humor for novels.
