From John Jenkins
Birmingham
When I breathe in it appears to me that the volume occupied by my body
increases owing to the inflation of my lungs.
It therefore puzzles me when writers such as Chris Goy (Forum, 8 February, p
47) suggest that, in order to squeeze as many people as possible into a small
space, they should all breathe in.
Surely it would be much more helpful if they all breathed out?
