Research by the Institute of Weird Thinkers has today published their conclusions on the causes of Nerdhood. Apparently, the study which investigated over 200 famous nerds found that 95% of those studied were in fact weird because they had a weirdly complicated childhood. Many sought refuge in a life of Nerdhood because they never felt in control as a child. Others took up Nerdhood to avoid social situations and more still became nerds because they wished to avoid this stupid, pointless life altogether - but didn't want to hurt themselves to do it.
Whatever the reason Nerds, keep doing it - or go and find a shrink.
