Take a good look at this picture. Wide-body aircraft cabin, spacious seating, smiling flight attendants and so on. Remember this picture the next time you climb aboard. I doubt that it’s the picture that will stay with you after the flight. It may not be appropriate for a man to discuss childbirth, but I can’t get its analogy to long distance air travel out of my head. The conventional wisdom is that a woman’s pain during childbirth recedes and is replaced by the pleasure she receives from the child. I can’t speak to that experience personally, but I can tell you that something inexplicable and similar happens to me with respect to very long passages in an airplane.
