If like me, you grew up before computer and video games, fMRI and PET studies show that you might be missing a part of your brain that Millenials have.

The exercise in this post, similar to the Stroop color-word test, seems to discriminate among Boomers and Millenials. It demands fast mental switching. Millenials zip through to the end with almost zero error; their brains are future-fit and ready to go. Most of us boomers, high achievers that we are, start strong but then fizz out near the middle. By the end, we have entered that-part-of-our-brain-where-there-is-nothing. Try reading the color not the words and see if you can get to the end with 90-100% accuracy in 25 seconds or less.
