In some affluent areas 6'0 feels just about average, I must say. That's just my perception, though, and height neurosis probably influences that. Scientific studies would be more reliable. But it seems as though 6'2+ guys are everywhere and sometimes even the norm in certain areas, and they get most of the attention and status, to the point that it's obvious when comparing them to guys bellow 6'0. I feel like I can't go anywhere without the lifts I wear to make me 6'0 when I'm in these kinds of places.
Prestigious universities and the workplaces of certain companies are a good example of places where the average height seems astronomically higher than in the rest of the world.
Again, this is just my perception, so please don't blast me for presenting this as if it were factually and actually this way. I know that it may well not be, but to a person with height neurosis, this is how it feels to me.
