[He does have a pause where he has a hand almost over his heart, thinking before he starts something that's an attempt to explain with a few vague hand gestures through it.] Being continually aware of everything would become distracting and make it difficult to focus on any one thing enough to function; the brain has structures dedicated to filtering input, sorting out what would be relevant and useful immediately for conscious notice, what may not be of immediate note but is worth remembering in the long-term, and what to essentially discard or work around without notice - any sensation that is 'continual background noise' long enough will eventually fall into the last category, only drawing attention when something about it changes unexpectedly.
