From Roy Murchie, Wivenhoe, Essex, UK
You recently ran a piece on the possible link between calorie restriction and longevity, commenting how difficult it is to run proper trials(18 February, p 17).
Has anyone looked at the UK population around the time of the second world war and soon after? Rationing provided a decent, though boring, diet for everyone. I was often peckish, but never starving. Rationing went on into the 1950s. I am 90 and I know many contemporaries who seem to be lasting well.
