If you know a second language, then you know it requires maintenance and practice to be able to stay fluent. The moment you stop practicing, the language starts to fade, until you find yourself barely able to ask where the bathroom is.
That’s called language attrition, and it isn’t limited to language. If you want your brain to work faster, you need to train it and maintain it. There’s no better way to do that than NeuroNation Brain Training, an app designed to improve your cognitive abilities. And right now, you can get a one-year subscription on sale for $39.99.
