Brain Training Games Don't Train Your Brain
Stoobalou writes with this excerpt from Thinq.co.uk: "A new study has shown that brain training games do little to exercise the grey matter. Millions of people who have been prodding away at their Nintendo DS portable consoles, smug in the knowledge that they are giving their brains a proper work-out, might have to rethink how they are going to stop the contents of their skulls turning into mush."
Regular exercise is still the best defense against an aging brain.
Learning a new language is a good one. it forces you to generate new cells. Learning a middle eastern language when you are a westerner will really speed it up as it is so radically different.
But that's not only for spoken language. learning a new programming language will also do the same thing.
Basically, find a subject and start studying.
Do not look at laser with remaining good eye.
Counterexample: try engaging in witty reparte with an arbitrarily chosen coder, and then repeat experiment with an arbitrarily chosen jock. Pro tip: you're subject should not get points for being "sharp" just because the wedgie you receive leads to stabbing pains.
People willing to trade their freedom of expression for temporary entertainment deserve neither and will lose both.
