After some help from the PR representative, my brain waves were plugged in and I then used headphones to listen to the app—aptly named Calm—tell me to get in a comfortable position, but sit up straight and relax my shoulders. For the first minute or so, the app needed to calibrate the seven EEG sensors embedded in the headband. I was prompted to think of actors. Immediately, I panicked. No names came to my head. All that would inexplicably flash in my mind was the opening credits of the TV show Friends. Then, Brad Pitt. Then, Jillian Anderson. I sat there thinking about how I couldn't think of any actors' names. Then I was prompted to think of TV shows. A similar string of thoughts ensued. And finally, I was told to think of shapes. I wasn't sure if I was supposed to think of the actual shapes or the names of shapes, but I wanted to do the right thing. "Rhombus" repeated over and over in my mind.
