plagues that make excellent breakfast cereal

So I've signed up to the free version of lumosity and then read about it. Apparently as a brain improving method, it excels at improving a person's brain to perform the tasks that they are doing at the website, but there is no confirmed evidence that it improves the brain with respect to any other ability.

This is why I have not paid to unlock all of the features at the site.

I will admit that my brain needs improving, but I have yet to find the best way.
