You may have noticed recent research which seems to demonstrate that ‘brain-training’ games do not lead to a more agile mind. They just make you more proficient at Super Donkey Derby, or whatever it is that you practice a lot. This has come as something of a gift to the Press who have been listing all sorts of things that are ‘proven’ to boost brain performance. I have noticed the following: eat fewer calories, maybe 30% less (!); eat more raisins, pasta, eggs, rosemary, basil, oregano, thyme, sage, cinnamon, turmeric (i.e. switch to a Mediterranean diet, eat curries, or chew a bouquet garni); drink more coffee or cocoa; read more, learn another language or play word games; make space to talk to your colleagues; get more exercise, especially running; work less, chill out; write stuff down; and don’t bother with fish oil capsules… Now you know.
