I've used lumosity free version or a few months. Since i stopped playing, I now forget even more stuff :-) 

How does this company work?

I have trouble empathising will some peoples mental health issues. I understand that we now know that in some cases (thats still alot of people) it's a horrible disease. In many I think it's just a lack of resilience and woe is me mentality brought about by the everyone gets a ribbon theory and the Facebook everyone else has a great and interesting life theory.

I'll be looking into this company as I think mental health is going to be here for the long haul and companies will have to, at least, be seen to be doing something about it.
