So, Mr Andy “Beanpole” Mabbett called me short. What he, and other lanky bastards don’t understand is that 5’6″ is the optimal height for a human being, and that is a fact proved by scientists.
The physics and biology are simple. If you are taller than the optimal height, not enough gravity reaches the top of the brain. This means that the blood tends to collect there, and not enough goes through the lower parts of the brain such as the hippocampus which controls things like spatial navigation. This is why tall people are often gangly and bump into things.
People shorter than 5’6″ have the opposite problem. Their heads are closer to the centre of the earth (where the gravity particles are formed in the base of volcanoes) so the blood tends to collect at the bottom of the brain and not flow so much at the top. This makes them more likely to commit suicide or suffer from an engorged hippocampus (which also controls long-term memory, which is why very short people like Hitler, Napoleon and Stalin never forgot grudges, for example).
However, at 5’6″, the distribution of gravity in the brain is perfect for optimal blood-flow around all areas, leading to high intelligence, superior wit, peak physical ability and extraordinary virility. Scientific fact.
Co-incidentally, I am five feet and six inches tall.
