We were going for the sort of Occam's razor, like cutting it down to the simplest sort of description.

A really important part of that story as well, Tom, is that at the same time myself and Andy were thinking about that, one Saturday I was sent up into the loft by my wife Leanne to empty it out because I think we were having, I don't know, we were having some new insulation laid or something.

So I went up in the loft and I get bored very quickly.

And there was this box up there of her old school exercise books.

And so the first one that I pulled out was a chemistry book.

And it was she was taught chemistry in Porthcawl in the early 80s in South Wales by this teacher called Mr. Clark.

And I started to have a look through this exercise book, and it was amazing.

exactly when you're saying like being the way we teach people so what how does that manifest itself i mean are you quite particular about certain routines which you you have to sort of really make happen
