Are you feeling stressed out? Enter MC Square’s X1 relaxation DAP which claims to "induce positive brain waves" in that thick skull of yours. It uses rhythmic light and sound (via goggles and earphones) to “improve concentration and memory, increase relaxation and improve sleep.”

Sound farfetched? It actually has US studies to back it up. According to researchers from Thomas Jefferson University, using this thing correlates with statistically reliable improvement in verbal memory, associative learning, working memory and measure of attention/concentration.

If your "senior moments" are increasing, then this $399 gizmo may be for you or belongs in someone’s holiday stocking.
