Carolyn McCann is the sole reason I passed chemistry in high school, but that is not why she is on this episode. Carolyn is an effort expert, because I have never seen someone with so much drive a determination. The coolest thing about Carolyn, is that drive and motivation comes from herself. We have been pals since the dawn of time, aka 2003. We met on a swim team, and she continued on to swim at Michigan, then completed her high education at Stanford. Right now she works as an engineer, and she goes into the interesting aspects of it that I am personally oblivious to. Carolyn sends some silly texts with a dice deciding the recipient, and it is hilarious!! Carolyn's choses cause is Be The Match, which is a database that connects bone marrow matches for medical care. She does a MUCH better job of explaining :-)
