That seems, I’m not sure the word, but not correct. You can find a doctor (any professional) to say anything.

I bring my phone and keep a book in the bathroom because I’m NOT straining. I sit down, and while gravity is doing its thing to my guts, I read a chapter. I’m not rushing or pushing or popping hemorrhoids because I’m on my phone writing a stupid comment about pooping while pooping.

I don’t think Dr Greg knows how people are using their phones in the bathroom. People aren’t reading the back of shampoo bottles because they’re in a hurry.
