Todd Fonseca is an executive in clinical research and communication for Medtronic and holds an interesting array of certifications including Certified Body Language Trainer. He is also the founder of the Anti-Networking Network Meetup and likes to ask meetup guests "What would be your superpower for an hour?" Needless to say, the interview brought interesting concepts to the floor and we had fun doing it.
The interview with Todd included short discussions on the placebo effect, situational awareness, and a lengthy discussion of Paul Ekman PhD's work on microexpressions. The seven key microexpressions (Happiness, Sadness, Anger, Disgust, Contempt, Fear and Surprise) are foundational to human communication and found to be universal - in other words, they exist among people everywhere on the planet. Our conversation delved deep into the identification and application of them. 
We grooved on the themes of the importance of having these microexpressions in our communication toolbox and talked about music from the Oh, Hello's and Robert Finley, an artist recently produced by Dan Auerbach of the Black Keys.
