Article from Business Insider with insight from internet squillionaire Max Levchin
(emphasis is the article author's own)In Silicon Valley — and the East Coast as well now — there are lots of successful companies with younger executives. The sport of choice where deals are made and ideas are thrown around and relationships are forged is definitely traditionally golf. That's where you don't have to sweat — you just walk around with people you like, and occasionally pretend like you're doing something physical [...] but it's not very quantified. It's just kind of aim, hit the ball, and pray. I'm sure the skills involved eventually remove the prayer necessity, but it's pretty open-ended.
So you have this current generation of young executives, and they're not particularly interested in walking around slowly. They want to do something physical, especially outdoors. They are very quantified, because that's definitely a thing now: It's not so much fitness as they are interested in fitness that they can measure. So the blooming of the Fitbits and Misfits the Jawbones of the world is all about people saying, 'I don't have to go to the gym, feel crappy for an hour, and be thankful that it's over.' You can actually see what you've done. The quantified-self stuff has perforated the popular conscience.
