I would want to see an analysis of variance. Groups should be Long haul, non flying, short haul and a control group. Variables would include hours at high altitude, frequency of coition, alcahol consumption, excercise (ha ha as if) etc..
I would also like to get all the women to do a dream diary and examine them for penis envy. I suggest that the statistical instrument be Goodness of Fit. Er did I say that one out loud?
