They Sure Do Have It All In This Plane

You know how sometimes you say things by rote and never think about what they mean? Well, one such thing is the cabin pressurization part of the predeparture speech. "The cabin is pressurized for your comfort and safety." Now safety I can see, because being able to breathe will contribute to one's safety. But comfort? At no time have I overheard a fellow take a deep breath and say to his wife, "You know, that sure was comfortable." Or heard her reply, "I know. Can you imagine how miserable it would be in here without enough oxygen to keep us conscious?"
Now that I think about it, flopping around like a goldfish on the floor of an airplane would be pretty uncomfortable. So maybe it is for your comfort.
