Want an argument? Grab old-school high school English teachers and ask them how many words should be in a sentence. For that matter, ask high school English teachers with a minimum of five years of grading essays under their belts. Listen.
Those veteran teachers will talk about essay length and paragraph length, but they won’t dictate a sentence length.
They know that only sentence variety and sentence maturity matter. Sentence length should be like the waves on the shore.
