My mother and aunt have always been my twin inspirations. First of all, they are actually identical twins. Though in many ways, their similarities are only skin deep. While my mother made a name for herself as a hard-nosed reporter before devoting herself to being a resilient, indomitable single mother to my brother and me, my aunt, Dr. Roberta Brinton, is the Director of the Center for Innovation in Brain Science at the University of Arizona.
