On the menu today for my right brain:
a few awkward left-handed tasks
a different walking route downtown
two rounds of Set®
and I picked up these two titles at Pioneer Book, with an old coupon I had:
The Brain Workout Book
More Creative Growth Games.
Also, I got started again with my Kundalini yoga this morning and then got out into the sun while it was still high. These may not be exclusively right brain activities, but you'll never convince me they weren't good for both sides of my gray matter.
