But does this imply licking it in a “lickable” state? I have a hard time imagining licking a gas, and licking hydrogen as a liquid at -250 C or so sounds, not great.

Specifically about that third point, how long would it take to get into a “livable” range if you were free-falling? Like obviously hypoxia is a legit concern, but are you going to get out of that range quick enough to avoid real complications?
