I made a Lumosity account earlier today just to see what it was like. I did the first little run though and found it to be, at the very least, entertaining. However, I am loathe to spend time on entertainment that is being alloted to training my mind and body. So my questions are thus: Does anybody here use Lumosity? If so, how was your experience with it? Is it worth the time expenditure or mearly an entertaining way to pass the time.
