It was created to bring to light certain people's sinistrality
along with raising awareness of the advantages and disadvantages of being left-handed in a predominantly right-handed world.
Also known as Sinistrality
(derived from the Latin word sinister meaning "left" as well as "unlucky") the issue of left-handedness has been studied theoretically and empirically for over a century without any definite resolution.
(Many works show him concluding not simply with the terminal line in a series of repeating signs, but by breaking the final trace midway.) Also relevant, one suspects, are the etymological associations of sinistrality
with awkwardness--the idea of the "gauche" that Roland Barthes would soon make central to his account of Cy Twombly's work--on the one hand (those repeating, deliberately "artless" signs), and femininity on the other (the gendered connotation of their pinkish tone).
For the most recent period, the combined ratio becomes lower than 1, which can be explained by a stabilized sinistrality
. Moreover, the figure reveals two important peaks in 1992 and 1999.
First record of sinistrality
in Poecilopsetta plinthus (Jordan & Starks), a pleuranectid fish of Japan.
For many years, researchers have also attempted to determine whether or not the left-handers in the human population have any special or good qualities that might be considered as an advantage of sinistrality

Left-Handers Day is an annual event when left-handers celebrate the advantages their sinistrality
in the southern and tawny mole crickets (Gryllotalpidae, Scapteriscus).
