If my father was left-handed and my son is left-handed, why then am I right-handed?

When you extend your right hand toward someone facing you, it is on their left side. Perhaps when your father was holding something in his left hand and extended it to you, he was typically putting it in your right hand. Thus you were prone to use your right hand more. Similarly, if you were holding items in your dominant hand (right) and extending it forward to your son, it would go to his left hand.\n\nHandedness can be influenced by environment. For instance, only letting a child use an implement in their right (or left) hand will make them right (or left) handeded. So the natural tendency to extend something straight ahead when facing a child will put the item in their opposite side hand.

I am a left hander and instresting that in my Computer Science class the majority of my friends were left handers and the only australian girl was a left hander. I did some art units and I was the only left hander in the class.\n\nSo I do think that there are special talents from what hand you are

Although some people said that left handed people die earlier than right handed people is not true because the sources I've seen are statistically inaccurate.  \n\nThe cause of left handiness is unknown at the moment. There's no concrete evidence of it being hereditary, The cause is still being investigated.  But, I can give a few facts first.\nMales are more likely to be left handed than females.\nOn average lefties make up 10% of the total population.\nA leading theory of left handiness is the amount of the male hormone testosterone is given during gestation.

You have simply found a unique viewpoint.  Americans, by percentage, are no more left-handed than any other culture.  The dominance of one hand over the other, at this point, seems to be a simply random occurance.  Right handed people, of course, ARE more prevelent..as is proven by the fact that most items used are geared toward right handed folk.  Speaking as an ambidextrous person, I have the best of both worlds..especially the time I broke my right hand. :o)

Very interesting question.  I haven't read anything about someone's brain being flip-flopped so that language areas would be on the other side of the brain.  But that doesn't mean it's impossible.  It simply means there isn't enough research on the subject.\n\nConcerning left-handedness, I got the following statistics from wikipedia.org (http://en.wikipedia.org/wiki/Left-handed#Statistics_of_left-handedness)  \n\n"Approximately 10% of the population is left-handed. People who can use both hands equally well are ambidextrous. True ambidexterity is rare.  Generally, there are about 10% more male left handers than female left handers (5.24% Male, 4.76% Female). Approximately one-third of identical twins are left-handed. [1] Statistically, the twin of a left-handed person has a 76% chance of being left-handed."\n\nI found some very interesting articles on dominance, cross - dominance, and ambidexterity.  I also found article on rare health conditions where organs are on the opposite side of the body.  (Such as dextrocardia, where the heart is on the right side instead of the left).  I know these aren't about being left-handed or right-handed.  But it goes to show that body parts can be in the wrong places.  I have provided links below.

Interesting note on this.\nMy brother and I have both trained at the same school for the same time frame. I am right handed and he is left handed. we are the same height, weight and build.\nWhen we workout together we draw a crowd as we match each others movements so well. When we kumite it is hard for us to hit each other cleanly, we usually land equal blows but on different sides. We are too evenly matched and similar, there is rarely a clean exchange.\n\nThis doesn't really answer your question but it relates to the left hand/ right hand thing.

Complain.\nI am appalled that the teacher is forcing your son to change hands.\nI am concerned that the school maintains a policy of making left-handers use 'ink pens'. There is no justification for this, especially when there are so many alternatives. The school should know that 'ink pens' are designed only for right-handers who can pull the nib across the paper; left-handers try (unsuccessfully) to push it.\nAsk the school what equipment it has for left-handers who make up about 10% of its pupils. This could be inexpensive things such as left-handed scissors and certainly suitable desks and work-spaces. If they have not, why not?\n\nI am left-handed. I taught Science for 25 years and made sure that left-handers had the proper equipment when they were in my teaching lab.\nDo not let your son's school discriminate against left-handedness.

Yes, USA - I am left handed and up until the sixth grade my teachers forced me to turn my papers like a right hander would and I was forced to throw right handed in gym and do everything right handed because they did not have the equipment to suit a left handed individual. When I was in the sixth grade my teacher noticed how difficult I was having to write that way and turned my paper. To this day I get complements about my handwriting thanks to her. I live in the USA and my children have had the same problem going through school. Not as much as I but still very segregated. Even at doctors offices and other public places it is suited to work for a right handed world. Notebooks for example are right handed suited. The binding is to the left and therefore out of the way when a right hander writes but the left hander has to rest there arm on the binding to write. Trivial I know bu still very frustrating.  It is getting better but we will never out number the right handers so therefore society does not see need for a change. It is considered a handicap.

A person who is left-handed primarily uses their left hand, more so than their right hand; a left-hander will probably use the left hand for tasks such as personal care, cooking, and so on. Writing is not as precise an indicator of handedness as it might seem, because many people who are left-handed write with their right hand and use their left for everything else.\n\nPeople who are left-handed are technically said to be sinistral, and left-handedness is sometimes referred to as sinistrality. Both words derive from sinister, the Latin word for “left”. This word in turn derives from sinus, the Latin word for “pocket” referring to the fact that the pocket in a Roman toga was on the left side, for the convenience of a right-handed wearer\nStatistics of left-handedness\nApproximately 10% of the population is left-handed. People who can use both hands equally well are ambidextrous. True ambidexterity is rare. See laterality.\n\nGenerally, there are about 10% more male left handers than female left handers (5.24% Male, 4.76% Female). Approximately one-third of identical twins are left-handed. [1] Statistically, the twin of a left-handed person has a 76% chance of being left-handed. [1]\n\n[edit]\nCauses of left-handedness\nNo one knows for certain why the human population is right-handed-dominant, but a number of theories have been proposed.\n\n[edit]\nEvolutionary theories\n[edit]\nThe warrior and his shield\nThis theory attempts to explain why left-handedness is rare by the position of a warrior's shield and his heart. Basically, since the heart is on the left side of the body, a right-handed warrior (who holds his shield with his left hand to free the right hand for a weapon) would be better able to protect his heart and therefore more likely to survive.\n\nThere are a number of objections to this theory:\n\nThe heart is not that far off centre. Protecting it with a shield would result in a weak selective pressure. \nThere have not been enough generations since the Bronze Age to make a difference. \nAnalysis of ancient cave paintings [2] indicates that humanity was dominantly right-handed long before the Bronze Age. \nSome believe it predicts that more men would be right-handed than women. However, data indicates that more males are left-handed than females. This objection also demonstrates a misunderstanding of heredity. The theory would predict that fewer left-handed males would survive but says absolutely nothing about ratios of male: female left-handedness after that time. Nor does it explain why there would be either right-or left-handedness to begin with. \n[edit]\nAdvantage in fist-fighting\nA variant of the above argument says that left-handed people have an advantage in fighting without weapons, because of the "surprise" factor. (This fact is well known to boxers and was employed to world-record effect on Nov. 4th 1947 when Mike Collins, a natural left-hander, emerged from his corner in a right-handed stance before suddenly shifting left and delivering the fight's first and last punch, knocking out opponent Pat Brownson in 4 seconds.)\n\nA 2004 study by Charlotte Fauriet and Michel Raymond of the University of Montpellier II in France, published in the Proceedings of the Royal Society, argues that there is such a link. To prove their theory, Faurie and Raymond surveyed nine primitive societies in five separate continents. Through a mix of direct observation and existing data, they estimated the number of left-handed people within each population. They also looked at murder rates, thinking that those communities with higher murder rates might favor populations with more left-handed people. The more violence, the more chances lefties would have at issuing their unexpected left hook, or other such weapon, and come out on top.\n\nAmong these samples, they found strong support for the idea that, at least in primitive societies with higher levels of violence, lefties thrive.

Lefty is  person who is more dexterous with his left hand than with their right hand. He will probably also use his left hand for tasks such as personal care, cooking, and so on. Similarly, Righty is a right handed person who is more dexterous with his right hand than with their left hand.\n\nDo select the best answers soon!

On your computer, go to "start" > Control Panel > Printers and Other Hardware > Mouse...on the tab that says "buttons", under "primary configuration", click "switch primary and secondary buttons".  Voila!  Now your standard right-hand mouse is a left-handed mouse!

Because most people are right-handed.  Because lefty's like myself are weird.  Give me a break!

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.
