There is something magical that seems to happen when you write something down.

So, and there is a lot of research on this.

I think there is something like more than 1,200 studies, and they all confirm the same basic result, which is writing stuff down about your emotions makes you physically healthier.

So the first study was done by a professor called James Pennebaker.

He's an American.

He got some of his students to just keep a short journal detailing an emotional trauma that they had experienced in their life, which he didn't have to specify what it was.

It was just anything which they considered traumatic.

What is double entry bookkeeping?

So what was the commonplace book versus the Sibaldone?

So, yeah, Zibaldoni is a Tuscan word and it means salad.

And it was literally a notebook which a normal person kept and they wrote down everything in it that they enjoyed, that they wanted to read again, that was either fun or useful.

So typically it was poems, Aesop's fables, chunks of Dante, chunks of Boccaccio, who were contemporary Italian writers, prayers that they particularly liked, stories from the classics, but also modern romances, songs, poems, etc.

Chunks of Bible stories as well.

And they did this because this is an era before print.

And if you wanted to have literature, written literature in your own home, it had to be written by hand.

Do you think that we might see some education systems, rather than going further down the road of using iPads in schools, reverting back to this commonplace book or some version of that way of education?
