What about all that cash you have got lying around the house? This is not about the children’s piggy banks, those euros you have not changed back or the stuff that has fallen down the back of the sofa.
Go into the kitchen, open all the cupboard doors and take a long, slow look at all that money.
Now do the same at the fridge and freezer – though it will have to be a much quicker look because you do not want to start a thaw.
