Sorry, you're telling me that nitrogen bubbles forming in your blood vessels isn't a big deal? It should be no different from decompression sickness, but more severe. Decompression sickness can be lethal if a bubble blocks blood to the brain or bursts an important vessel and causes internal bleeding. At the very least your mucus membranes would rupture and start gushing blood.
I mean some people get a severe nosebleed from a change of a few hundred feet in altitude...
We all know about decormpression sickness here (See previous page). However, your previous statement is still wrong on several accounts
Also in low pressure the boiling point of water is lower, so your eyes and mouth would likely freeze.
I'd like to submit that a frostbitten tongue is entirely secondary to boiling* blood bursting** out of every vein in your body.
* Boiling indicates that fluid would have a phase transition. What happens is the forming of Nitrogen bubbels in the veins, not the boiling of the blood itself
** Except for weaker veins, for example in the nose, none of the veins will burst. Blocked bloodflow is a more severe problem. Besides, even if they did, they still would have to go through your hide.
Really, the way you formulated you statement and the post you reacted too indicated that you were reffering to the common misconception that due the near nonexistent pressure in space, your blood would litterally boil, as opposed to the decompression mechanic, as described in the post above and on the previous page.
