Why Do I Feel So Much Better After a Transcontinental or Transoceanic Airplane Flight When I Have Been Sitting Up in the Front of the Plane?

I mean, the free mimosas, the extra space, and the extra degrees of recline in the seat shouldn't do really be enough to do it, right?

Am I really such a dominance junkie that getting picked out of the herd and being told that I am special for seven hours makes that much of a difference?
