I weigh in a shade under 70kg sans handbag - BMI comfortably in the "normal" range..........taller than average, I suppose, but I'm no supermodel.
To my mind the BMI index works well for women but is unfair towards a lot of muscular men. My Beloved is close to the height/weight of Frank Bruno when he was fighting....but apparently he is "obese"
Pilots, as a group, are likely to be slightly heavier than "average" being skewed towards the middle-aged, higher income, desk jockey type. Or do I do them an injustice?
