Operation - Simulate Right Hand

I was thinking when humans started writing what made writing with the right hand default?

So until a person is lefty every thing one does is pretty much using his right hand. As far as I know when we were in school we were always guided to write with the right hand and the teacher never said that hold the pencil in your left hand.

So unless you have it in your genes to write with your left hand you never even try or think of doing it.

Is it not analogous to being mechanical and having formats, standards and conventions? Does that make us machines but a more sophisticated one? Or the standards are built after many years of researches and imposed on every one so that we do not have to reinvent that writing with the right hand is the best or is not?

Any ways these crazy things catch some one like me very quickly. So I decided to simulate my right hand using my left hand. I started writing with my left hand a few months ago. At first I was barely able to make the alphabets. But now I can write sentences, of course the speed is compromised.

Here is what it looks like when I write with my right hand ...

And here is what it looks like when I write with my left hand...


I am sure with some practice I will be able to write so well that one cannot tell whether it’s with the right or the left. Let's see how far I go..I will keep posting the progress.

Question:
What is the one thing that you can do with your right hand but cannot do with your left hand and vice versa?

Thought:
If u s can be us then why did we waited till the SMS era to come and some one suddenly realized that u r can be your.
I guess limitations in the number of letters lead to such modification and the acceptance of it other wise it would just have been a horrific spelling mistake or result of dyslexia.
