Over the past few years there has been a scarcity of midgets available for dwarf-tossing contests in North America and there is a scientific reason for this. (Aside from those stupid politically correct reasons!)
They do not, and never have, reproduced in sufficient numbers to make themselves noticeable amongst the general pop[ulation!
Now you may wonder why this is so..., and this is where the scientists come in!
It seems they have found out that "little people" still have normal-sized penises and this constitutes a greater percentage of their total body mass compared with regular-sized men.
Because of this..., when they get an erection the required blood flow to the penis is proportionately larger than full-sized people and could (and does) result in decreased blood flow to the brain.
This will cause a dwarf or midget to become light-headed or even pass out....., and this makes procreation extremely difficult for our little friends!
As a result, they don't have sex as often as normal-sized men and women and it keeps their numbers low!
The way I see it anyway!
(We have a video from when they were much more common amongst the population)
