Those words are a bit of a mouthful, not. The chin shouldn't have to wag until it aches. The brain should have to absorb too much at once, or else it's likely to fart out every single letter.
It is surely far better to half-bake your idea and then start another completely fresh sentence, rather than try to cook the whole recipe at once with every single ingredient fully exploited in one long-winded phrase.
Of course, we don't want sentences that are so short that our prose sounds like it's copied straight from a 'Janet and John book', do we Mr. Hemingway? But yes, we agree that it's wise to avoid trying to tame too many letters.
"I'm not going to get into the ring with Tolstoy." (Ernest Hemingway)
