This is my example of ‘over-writing’ – where a character says more than needed (when he goes on about gut bacteria). 
It’s a risky strategy, because you may create a tedious script. 
And whilst other filmmakers may disagree with my approach, I’d much rather have more material to cut away in the editing room, than be scrambling around with too little material at the end.
It’s also an example of calling-out the audience – if anyone starts falling asleep here, the protagonist is saying, ‘hey wake up, this is important, I’m talking to you’.
