Ah yes, you do have to be at 62K for water to boil; however, the nitrogen in
your blood turns to gas at much lower altitude. (For most people it is
below 50K.) This phenomenon is what is commonly referred to as "your blood
boiling."

Experiencing the "bends" is not pleasant!

To get water to boil at 38C (body temperature) you need a pressure of
0.066 bar. The International Standard Atmosphere gets to 0.,065 bar at
19km, which is 62,000 feet. Just as a matter of interest.
