The structural modifications to the human throat that permit easy speech make us vulnerable to choking. If I recall correctly, most animals can breathe and swallow at the same time. Human infants are also capable of this. But the larynx slowly shifts so that we can modulate our airflow in sophisticated ways, and one consequence of this is that swallowing is no longer safely compatible with simultaneous breathing.
Voted up from -1 because this plausibly is just an honest misunderstanding.
Though Annoyance, you should keep it in mind whenever you're tempted to interpret someone's remarks in a way that seems surprising / non-sequitury... I guess to you the world just seems like an endless stream of people saying crazy things, and so you can't distinguish your own misunderstandings of them within that.
(Epistemic) rationality has two major components:
Attending takes time, energy, quiet, etc. Circumstances where human rationality degrades include when:
It seems relatively easy to test rationality smarts; repeatedly give folks info and time to work new problems and measure their accuracy, calibration, etc. And I have an idea for testing for rationality toughness: compare performance on info-similar pairs of good/bad-circumstance problems.
For example, assume people are better at evaluating if a spouse is cheating when considering an acquaintance in their social circle, relative to a stranger or their own spouse. If so, we could pose them a pair of problems with very similar info structure, one with an easy spouse and one with a hard spouse. The closeness of their response in these two cases would then be a measure of their rationality toughness.
Of course this test may fail if the similarity is too obvious, or the pair are asked too closely in time. But maybe we don't even need to ask the same person the two questions; perhaps we could usefully compare someone's answer on a hard question to answers from a pool of similar people on matched easy questions.
While I haven't thought this through, it already suggests a training technique: consider matched hard/easy circumstance problems and compare your answers, separated by enough time that you forget most of your previous analysis.
