'Unlike any other organism in history, humans have a mind-body conflict: we have a body built for performance, but a brain that's always looking for efficiency.' We live or die by our endurance, but remember: endurance is all about conserving energy, and that's the brain's department. 'The reason some people use their genetic gift for running and others don't is because the brain is a bargain shopper.'
For millions of years, we lived in a world without cops, cabs, or Domino's Pizza; we relied on our legs for safety, food, and transportation, and it wasn't as if you could count on one job ending before the next one began. Look at !Nate's wild hunt with Louis; !Nate sure wasn't planning on a fast 10K immediately after a half-day hike and a high-speed hunt, but he still found the reserve energy to save Louis's life. Nor could his ancestors ever be sure that they wouldn't become food right after catching some; the antelope they'd chased since dawn could attract fiercer animals, forcing the hunters to drop lunch and run for their lives. The only way to survive was to leave something in the tank - and that's where the brain comes in.
'The brain is always scheming to reduce costs, get more for less, store energy and have it ready for an emergency,' Bramble expained. 'You've got this fancy machine, and it's controlled by a pilot who's thinking 'Okay, how can I run this baby without using any fuel?' You and I know how good running feels because we've made a habit of it.' But lose the habit, and the loudest voice in your ear is your ancient survival instinct urging you to relax. And there's the bitter irony: our fantastic endurance gave our brain the food it needed to grow, and now our brain is undermining our endurance.
'We live in a culture that sees extreme exercise as crazy,' Dr. Bramble says, 'because that's what our brain tells us: why fire up the machine if you don't have to?'
