` No, not at all, Colin. What it explains is that in addition to being

Nevertheless, he is correct. The only place gravity really comes in
to play in breathing is on exhalation, where the weight of the
chest can be sufficient to deflate the lungs, but there are
muscles to assist that action, which is why we can breath in
a weightless environment.
