this liquid is "flowing" around your head, hair, nasal passages, ears, etc
[and thus also may get contaminated with shampoo and cosmetics etc].

  Or inhaling loose hairs or the effects of the body's other `sewage outfall'!

  The answer is obvious: in real life the suit would have a mouth-and-nose
mask, or possibly a seal round the edge of the face. The fluorocarbon liquid
would be too expensive anyway to fill the whole suit with it.

  (In the movie they had to show his full face to let his personality show,
and that overcame practicality. Compare that:-
  (a) In a TV marine biology series that I saw, the diver wore a shallow water
aqualung diving suit with a large bubblehead helmet (and also so she could
talk to the camera without sounding `gasmasky');
  (b) In `Star Wars', in the space fight, the goodies had open faces and the
baddies wore fighter pilot masks.)

  How did divers in the old hardhat suits after a century of experience with
them cope with urgent natural function demands? (Some used a big napkin.)
