Wim Hof climbed Mount Everest in shorts, can hold his breath for five minutes and can fight off disease with his mind. Now he wants to teach you. ... Hof is one of the world’s most recognized extremophiles. In 2007 he made headlines around the world when he attempted to summit Mount Everest wearing nothing but spandex shorts and hiking boots. He has run barefoot marathons in the arctic circle and submerged his entire body beneath the ice for almost two hours. Every feat defies the boundaries of what medical science says is possible. Hof believes he is much more than a stuntman performing tricks; he thinks he has stumbled on hidden evolutionary potential locked inside every human body. ... Participants have come from across Europe and America for this seven-day training program aimed at extending control over the body’s autonomic processes. The human body performs most of its daily functions on autopilot. Whether it’s regulating internal temperature, setting the steady pace of a heartbeat or rushing lymph and blood to a limb when it’s injured, the body, like a computer, uses preset responses for most external stimuli. Hof’s training aims to create a wedge between the body’s internal programming and external pressures in order to force the body to cede control to the conscious mind. He is a hacker, tweaking the body’s programming to expand its capabilities.

Meditation and mindfulness are the new rage in Silicon Valley. And it’s not just about inner peace—it’s about getting ahead. … Across the Valley, quiet contemplation is seen as the new caffeine, the fuel that allegedly unlocks productivity and creative bursts. Classes in meditation and mindfulness—paying close, nonjudgmental attention—have become staples at many of the region’s most prominent companies. There’s a Search Inside Yourself Leadership Institute now teaching the Google meditation method to whoever wants it. The cofounders of Twitter and Facebook have made contemplative practices key features of their new enterprises, holding regular in-office meditation sessions and arranging for work routines that maximize mindfulness. Some 1,700 people showed up at a Wisdom 2.0 conference held in San Francisco this winter, with top executives from LinkedIn, Cisco, and Ford featured among the headliners. … These companies are doing more than simply seizing on Buddhist practices. Entrepreneurs and engineers are taking millennia-old traditions and reshaping them to fit the Valley’s goal-oriented, data-driven, largely atheistic culture. Forget past lives; never mind nirvana. The technology community of Northern California wants return on its investment in meditation. … It can be tempting to dismiss the interest in these ancient practices as just another neo-spiritual fad from a part of the country that’s cycled through one New Age after another. But it’s worth noting that the prophets of this new gospel are in the tech companies that already underpin so much of our lives.

For a decade and a half, I’d been a web obsessive, publishing blog posts multiple times a day, seven days a week, and ultimately corralling a team that curated the web every 20 minutes during peak hours. Each morning began with a full immersion in the stream of internet consciousness and news, jumping from site to site, tweet to tweet, breaking news story to hottest take, scanning countless images and videos, catching up with multiple memes. Throughout the day, I’d cough up an insight or an argument or a joke about what had just occurred or what was happening right now. And at times, as events took over, I’d spend weeks manically grabbing every tiny scrap of a developing story in order to fuse them into a narrative in real time. I was in an unending dialogue with readers who were caviling, praising, booing, correcting. My brain had never been so occupied so insistently by so many different subjects and in so public a way for so long. ... I was, in other words, a very early adopter of what we might now call living-in-the-web. And as the years went by, I realized I was no longer alone. Facebook soon gave everyone the equivalent of their own blog and their own audience. More and more people got a smartphone — connecting them instantly to a deluge of febrile content, forcing them to cull and absorb and assimilate the online torrent as relentlessly as I had once. ... Then the apps descended, like the rain, to inundate what was left of our free time. It was ubiquitous now, this virtual living, this never-stopping, this always-updating. ... the insanity was now banality ... e almost forget that ten years ago, there were no smartphones, and as recently as 2011, only a third of Americans owned one. Now nearly two-thirds do. That figure reaches 85 percent when you’re only counting young adults. And 46 percent of Americans told Pew surveyors last year a simple but remarkable thing: They could not live without one. ... By rapidly substituting virtual reality for reality, we are diminishing the scope of this interaction even as we multiply the number of people with whom we interact.
