I've been meaning to give 'brainHQ' a shot. If you haven't heard, it's a computer app for cognitive skills, and supposedly it avoids the pitfalls of 'lumosity' and similar apps in that the training carries much better to overall brain aptitude. I'm not 100% sold on it, but its low cost and they did one study on veterans showing that it fared better than other games, so I want to give it a go

I had a look at it and that sounds interesting. Would you mind sharing your experience once you know more about it? Thanks a lot! And all the best to you.
