Kevin Kelly (Episode #218)
This guy is one of my heroes. Love what he said in particular about the future of the QS movement. I've been playing around with data tracking HRV using a Polar H7 plus SweetBeatLife app on the iPhone but it doesn't really inspire me apart from the output of a fun graph.
Also I think the "get your Facebook friends to shock you if you don't go to the gym" thing is a total fad and also hugely open to abuse. I don't think that's going to take off... Except for maybe in fetish scenes.
