Left or right?

Ever wondered why you use one hand more than the other or for that matter, why are you right handed? Yes, I am confident that most of you readers are right handed and hence the earlier question- why RIGHT handed. Less than 10% of people around the world are left handed. Sorry lefties!!! Most of the further discussion would be from the perspective of righties!!!! ‘Us’ would mostly mean righties!!!

The majority of tools and equipments are suited for right handers, more than left handers. The door knobs are one such example though these days I myself have seen a number of left handed knobs. The taps and screws are another example which I find interesting. For us Indians, who usually eat with our hands, tap is not a problem as more often than not we have to open the tap with our left hand. But imagine tightening a screw or capping a bottle. Right now, to tighten the screws, you follow a clockwise direction – remember – tightening requires more pressure and accuracy most of the times and you would like to have your hand in a comfortable position for the same. To loosen the screw, only the initial jerk is necessary and the rest of the action is pretty straight forward. Yes, clockwise is much more comfortable than anticlockwise while tightening and vice-versa. The primary reason is the set of muscles in our hand involved. You can refer to supination (for clockwise movement) and pronation (for anti clockwise) for the details of muscle movements.

Another tool is the scissor. Most scissors are for right handed people – handle blade and all. A right handed scissor is one when you hold while cutting, the hand having the thumb faces outside. For lefties, this could be a problem, even if the screw is a little loose as all control is lost.

Lefties also face another problem – that of writing. Usually most of the lefties hold their pen/pencil in a peculiar fashion. They are forced to do it because otherwise, they might smear the ink of the previous letter written with their own hand. This is true for most of the written languages.

In sports, handedness plays a major role. Let’s take cricket – India’s favourite sport. Though bowling and fielding determines whether a person is righty or lefty, some people do wrongly believe that a left handed batsman is a lefty by birth. Actually, the terminology used should be top handed or bottom handed. Yes, a left handed batsman who is a righty by birth is top handed and a right handed righty is bottom handed. For top handed people, it is more like they are hitting a back hand shot (lets say in a game like tennis) with some support from the other hand. So if you are playing a game like tennis or badminton, your preference for backhanded shots might determine your preference in cricket. Now, which is better – being top handed or bottom handed? A left handed batsman has his dominant side – the right side facing the bowler which will give him more confidence. Not only that, there is this concept of right eyed and left eyed people i.e. a right eyed guy uses more of his right eye than the other. Most righties are right eyed and so on. So a top handed batsman would not only be using his dominant side, but can also see the ball more clearly with his dominant eye nearer to the ball. So he has more time than the bottom handed batsman and can execute his shots much better.

No prizes for guessing why Sourav Ganguly had such sweetly timed square cuts. Sachin Tendulkar is more of an enigma. I have read that he uses both hands and I have seen him autograph with his left hand. But I am not very sure if he has practiced that as he still bowls and throws with his right hand. In one particular match, I remember him trying to throw with his left hand and believe me it was not a pretty sight to watch. The ball somehow did reach the keeper’s gloves and the batsman of course couldn’t complete the single. But Sachin himself was all unbalanced and had thrust himself in the air.

Rafael Nadal is right handed but plays tennis with his left hand. It seems he used to play a double handed forehand. This gave his uncle and idea that Nadal could play left handed tennis. Now he  uses a double handed backhand too.

I guess this is enough for now. Read my next post to understand the science behind handedness.

    good interesting blog…

    what comes to mind is that because more than 90% ppl are righty…. what might have driven majority of tools and equipments being suitable for right handers is more to do with the thumb positioning of the right hand and its utilization to rotate bottle caps, screws, taps etc… the thumb naturally plays a big and important role for everyday tasks….

    and i guess the 2 hits you have got from Canada on ur post is most probably mine 🙂

      hmm. Yes, the thumb positioning is what is determining whetehr the movement is clockwise or anticlockwise. And the position also determines the muscle movement as each finger is connected to a different set of muscles. Thus, if i understand correctly, way we are on the same page.

    Did you know that sourav ganguly hit a century against SA in 2000-01 playing right handed ??? …. see this video to believe it — http://www.youtube.com/watch?v=jO_q9nGerPw 😉

    The smiley has been put in for a reason 🙂
