But I saw that I was faced with a body that was in bad shape because of the “software” that was running on its brain. There is a movement — at the moment a weak signal among “alpha geeks” predisposed to obsessive tendencies — preoccupied with measuring and quantifying the self. The idea itself isn’t new: notice and measure things about your “software” and your “hardware” and then try to affect them. But as ever, technology trickles down to the consumer and makes what used to be difficult easy, and what was once obscure accessible.
