No matter if it's early morning or late evening, when someone asks me how I'm doing my usual response is "Tired". It's become a common response, but I never realized how much truth was behind it. Until recently.
Flying used to be a classy adventure. You'd wear a suit, sit in a comfortable armchair-like seat, light up a cigar, and end up at your destination before you finished your third Jack and Coke (which was served by a smoking hot flight attendant).
