Just came across this site called Lumosity that offers "a complete brain fitness program" developed by neuroscientists at Stanford, UCSF and McGill who have formed Lumos Labs, "a cognitive neuroscience research and development company that builds software tools for improving brain health and performance. Lumosity is the first general brain fitness program from Lumos Labs."
I have to admit, I like the concept of brain fitness. Plus, it gives me an excuse to play games and pretend I'm doing something more valuable than indulging in chronic sudoku syndrome.
