There are two simple solutions to the super-rich quitting the country to avoid tax (Flight of the non-doms: how worried should Labour be about the super-rich leaving the UK?, 7 July). Tax all UK citizens wherever they live on their global income and assets. The US and Australia already do this, so it is hardly radical. And treat all owners of UK residential property as domiciled in the UK for tax purposes. Might even bring down London house prices.

• The study that shows a link between slower cognitive decline in old age and ownership of dogs or cats (5 July) will certainly not be a surprise to most pet owners. But are the researchers oversimplifying this? Correlation is not necessarily causation. Perhaps people who choose to own cats or dogs are genetically disposed to better cognitive performance in old age.
