Normal is a myth. Normal distribution is the truth.

The concept of a ‘normal’ person, as any psychologist, people watcher, nerd or pedant will tell you; is an impossible idea. When we say ‘normal’, we sort of mean average. Mean. So the mathematicians will say “You can’t have a family consisting of 3.76 people” Unless you count a child age 12-and-a-bit as 0.76 of an adult. So mean doesn’t get us anywhere if the data is non-continuous.
In the Health Survey for England (2008) the average height for a male was 5ft 10in and 5ft 4 ½ in for females. This leaves me wanting an inch, but what woman isn’t. So if I were talking to a woman I’d just met, and I was thinking “gosh, this lady seems terribly nice and normal” I would firstly admonish myself for using the word gosh, even in my inner monologue, secondly, I would deliver myself a sound cerebral thrashing for such a clunky, british oxymoron as terribly nice, then I would consider that she was probably 3 or 4 inches taller than me, making her not the ‘normal’ height but 2 or 3 inches above that. She is however on the bell curve in the centre, roughly. She is comfortably in the middle, in the fat bit of the standard deviation graph. Actually, so am I.
Especially if tiny people and giants are considered, I am positively average, a speck on the sexy rolling shoulder of that curvy bell distribution.
Bell curves are the truth because you are on one. You might be comfortably in the fat middle bit, you might be in the slimmer parts lower down, or you might be cramped in the sharp pointy corners. Either way, you are there somewhere. If you are not on it, you are dead or they have had to move the goalposts in order to squeeze little old you in.
Bet your bollocks to a barn-dance though; even though you might be right in the pointy, skinny corner, there’ll be someone taller, more curvy, faster, stronger, blonder, louder, livelier etc, etc, etc ad nauseum.
Normal is a thing we pretend to have or a thing we pretend to want when we have made sacrifices and compromises for our lives. I have met very few people who want to be ordinary. And the people that I know that want to be extraordinary, fall into the normal distribution. Take X-Pop Idol On Ice. The plebs fall into a bell curve.

As you can see from the graph, a very low (but well published) number of indescribably talentless individuals appear on X-pop, also a very low (but well published) number of indescribably talented individuals appear too. Unfortunately, the majority of the show is dedicated to those in the fat bit of the graph. There are many, many, many, many, many, many, many, many, many, many, of these people. Children who were never told “No, you are never going to be Beyonce; you’re ginger and you can’t hold a tune” arrive in their teens and adultness at the gates to audition. In fact, a survey said that one person in the UKis disappointed by a group of judges who tell them they have an ‘average singing voice’ every 9 seconds. (SMUOtS, 2011)
Can we keep just the ones at the skinny end on the right?
