Geoff, Regarding the air pressure question, it was once explained to me
that in one of the science fiction movies an astronaut was kicked out of
the ship without his helmet on. His face bulged out somewhat, presumably
due to the small but significant tissue pressure arising from blood
pressure. This is an extreme case of low pressure, and not a very useful
one, as the important point was, I think made earlier, that the pressure is
applied from most directions and hence cancels itself out. I suppose the
tissues equilibrate with the pressure and transmit it throughout the body,
especially when you do not have a sinus infection.
