So I think its a good idea to keep my brain trained just for life in general from work to school to household chores. I used to have a Lumosity account which my father paid for, and from what I remember it helped a lot with concentration and memory. Back then I think there was a way to use Lumosity for free and now its pay only, but I am on another site called Neuronation which trains the brain as well though I am not sure if it is as good. Neuronation trains memory, calculus, logic, perception, and language, but doesn't really measure attention though I notice I am less likely to miss things or make dumb mistakes as before I started on neuronation. The main reason I am on Neuronation and not Lumosity is because Neuronation is free. If they were both free I would use both to give my brain training sessions more variety. So I am wondering from anyone who has used brain training websiteso you think Lumosity beats all, or do you think all brain training sites are just as good? Also, are there any brain training websites you would recommend?
