Variability is ubiquitous in our Universe and applies to everything (from galaxies to bees wings and most likely even present in the quantum world) and specially visible on living things [Kinsey]. That means all distribution curves of about any characteristic of a population has very, very long tails.
Thus, "normal", specially in a population, is always a broad area; a very large and fuzzy region around the mean.
The number of people that falls exactly in the mean is not very different and can be even less than the people who think that they are at the end of the curve. And one may fall exactly in the mean in one characteristic and in an extreme point for another.
For a list of characteristics most of us will make dots across a very large region of the normal curve.
