True, but this has nothing to do with my statement above.

Please read my previous message. I pointed out that the air is warmed as
it enter the lungs and the temperature will be somewhere between room
temperature and body temperature (as I stated). And clearly, the longer it
stays in the body, the closer it will get to body temperature.

But that's not the point I was discussing above.

I was discussing the fact that air temperature is NOT changed by the speed
with which it is moved.
