An intriguing  account of someone who taught himself an unusual skill.

Are you alright? And I said “Yes” which was not true.

What I did and nobody taught me to do this.

I would start the line with one hand half way along it and not at the beginning

and then I would read the second half of the first line I’d do that with my right hand

and my left hand would go down the line and start to read that,

then the other hand would join it.

So what I was actually doing was reading half a line with one hand and the other
half the line with the other hand

and my left hand would go down the line and start to read that,

and then the other hand would join it.

So what I was actually doing was reading half a line with one hand and the other
half the line with the other hand

But reading them simultaneously and then putting it together

and then I gradually got faster and faster.
