test sinistrality.

Sinistrality is not the art or obsession of being sinister (as far as superstition, that probably is the meaning), sinistrality is lefthandedness. It seems to still have a stygma because many people need to find a reason to think that they are better than the other person. Scientist don't know the reason why some people are left-handeded while most people are right-handed. Some speculation is that the DNA helix is right-handed (clockwise), some speculation is that it might have to do with the Coriolis force (the force that makes water spin down a drain according to the hemisphere that you're in) during birth.
