I share this view. It's also an opportunity for me to share my view on consumption and digestion. When I schedule myself for critical listening, I strive to reach a state of balance - where I am neither full or hungry. And hopefully after I've done a fair amount of digesting from the previous meal. I also avoid most/all dairy that could potentially leave me congested.
Outside of any critical listening and I'm likely to sit down with with a bowl of Peach Cobblah & Haagen-Dazs Dulce de Leche during the session!
