Many things that we take for granted or have strange fetishes over - not only computers - have unsatisfactory origins.
Dating back to 3500 B.C., early depictions of high heels could be seen on ancient Egyptian murals. These murals would depict Egyptian nobilities wearing heels to set them apart from the lower class, who would normally go barefoot. Heeled shoes were worn by both men and women, and most commonly for ceremonial purposes. However, high heels also served a practical purpose for Egyptian butchers who wore them in order to walk over the bloodied bodies of animal carcasses.
