I'm not a lector and I don't play one on TV. But I've heard quite a few over the years and the best lector I've ever heard was a woman who was in her 60's, I guess, mother of 6, all of whom are older than me and grown. She read the long passages from the Old Testament as if she was reading a bedtime story. No greater emphasis on passage or interpretation, but phrasing and timing. The pauses were just right. She pronounced the words so that we could understand them. It was just really good. God rest her.
Wanna bet she this from habit :-).
