I think that one important factor, perhaps the most important one when it comes to developing a neurosis, is the family's average. Being 5'10 is around 1,5 inches below average in my environment (people my age), but probably 4 inches below my familiy's average. My height neurosis would be a lot less strong if my dad or my cousins would be my height. Instead they are 6'3+, even some of the women in my family are taller than me.
