That's an incredibly clear explanation of almost everything, Cato and many thanks for the considerable effort you put into setting it out in such a lucid way. I now understand everything with a clarity of the kind Hubble first provided in relation to distant galaxies.

I say 'almost' above. Do you think SGH is a good investment or not, Cato? Can you be a bit clearer on this?

And what does: "Trust is a matter of fish" mean? Or is it my glasses?
