Morrisons phone line | Two-metre distancing | Panting jogger | Testing shambles | Alien civilisations

I would like to put in a good word for Morrisons, the only supermarket with an intelligent management. Because they understand that elderly, self-isolating people may not be computer-literate. Other supermarkets only sell their goods via computer and answering machines. But if elderly customers ring Morrisons' special line, they are answered by a real live person who takes their order by phone.

Your article (Scientists report flaws in WHO-funded study on 2-metre distancing, 14 June) states that Critics of the distancing advice ... seized on the research, which suggested that a reduction from 2 metres to 1 metre would raise infection risk only marginally from 1.3% to 2.6%". According to my arithmetic an increase from 1.3% to 2.6% is a doubling of the risk. Hardly marginal.
