This would include people that used the left hand to remove defecation in olden times.  Sorry, I know this is a bit "earthy," but it's where it comes from, added to the fact that ancient people considered the left side the "evil" or gauche side of the body.

The correct position is similar to the way right handed people hold it, but almost all left handed people bend their fingers so they face their belly instead of out like right handed people because their teachers didn't know how to show them ( This may be an old stereotype, I don't know but when I was young fingers faced the belly).  In any case, if you are a natural leftie do what feels natural to you and don't listen to anybody then you won't have problems.\nI was forced out of being a leftie.  My son is ambidextrous; he was a leftie, but his piano teacher asked if she could make him use his right hand.  I told her she couldn't make him, but wouldn't mind her letting him use both hands.  My baby seems to use both hands too.  My son uses both hands with his fingers facing out not towards his belly like most right handed people.

Lefties tend to be more artistic since they use the right side of the brain.  Right handed people tend to be better with analytical issues since they use the left side of the brain.  There are less left-handed than right-handed people, but that makes them more special!! =o)

In some countries it is worn on the right hand.  However, in the US and most Western countries it is worn on the third finger of the left hand.

The custom in the middle east to this day is use the left hand for personal needs and the right hand for greeting and eating.  The Bible does tell that he washed the feet of the apostles, and that his were washed by tears.

The "left handed" or "sinister" side was thought to be affiliated with the devil by ignorant people.  As with many other things, people feared those who were different or in the minority.

Stewardesses; \n\nI believe this is the longest word which can be typed with one hand (left) when typing in the correct manner.
