For those of you con­cerned with brain health, here is another site to check out. Lumosity.com offers some free and paid resources for peo­ple who want to keep their brain in good shape. In either case, the first week of pre­mium mem­ber­ship is free, and does not require any credit card infor­ma­tion or the likes, so giv­ing it a try is as risk free as sign­ing up for a newsletter.
