Great for Mid 30-40 year olds who want to stay SHARP!
Since I have started playing about maybe 4 years ago I have become sharper at task that require more focus as well as paying closer attention to details and oddly became better at doing certain math that I need daily while working. They cater it to your specific age range and I believe it is fantastic at what it does to keep you learning and able to be as sharp and witty as you were in those years of youth. I believe it has helped become better at everyday daily task and makes it easier for you to learn new things faster. I try to introduce it to all of my close people but you always have to remember that you have to do the work and want to be better for yourself first.
