Is working out at the 'brain gym' really worthwhile?
After forgetting his PIN number twice in the same week one of my friends has decided his brain is just a bit out of shape.
His solution? Spending several hours on Lumosity, a brain-training program that includes close to 40 games and exercises aimed at sharpening memory skills, improving concentration and thinking faster.
And he's not alone, it seems. Some 14 million people around the world either subscribe to the company's website or have downloaded one of its iPhone apps.
Just as you can tone up your body by lifting weights, the types of games that Lumosity and its competitors like MindSparke and Posit offer are supposed to make your brain stronger and help it work more efficiently. That’s key for all those people who show signs of aging or memory loss.
