From Geoff Harding, Sydney, Australia
I have an idea regarding lifestyle approaches to try to reduce the chance of developing Alzheimer’s disease (6 November, p 46). Older people aren’t in a position to wait for a drug cure, so every beneficial lifestyle strategy should be practised.
Two important ideas have been suggested: getting seven hours of sleep and taking on a cognitively challenging activity. These can be combined if you study a difficult language such as Latin just before bedtime. In my experience, sleep follows quickly.
