In my sometimes desperate search to figure out my health, I did genetic testing. I signed up for 23 and Me, was sent a kit, did some spitting, and about six weeks later, became the proud owner of answers about my genetic self. Everything is presented in percentages, with statements like, 50% of customers who are genetically similar to you have detached earlobes. 
Largely, the answers were to questions I would not pay to discover. For instance, genetically, I am likely fair skinned and freckled. Or, I am predisposed to taste bitter and prefer sweet to salty. Of course, I forked over money because it tests for 41 different carrier status traits. Unfortunately, it turned out to be a dud on the genetic smoking gun or “here’s the reason your pancreas is giving you such sh*t” front, but I did get tremendous amusement from one factoid about my ancestry. Apparently, I have more Neanderthal variants than 99% of their 23 and Me customers. Yep, I am pretty much directly descended from Neanderthals. Who knew?
