The Science of Thinking Smarter - HBR.org: "Nowadays, our stresses are measured not in moments with mountain lions, but in hours, days, and sometimes months, as we deal with hectic workplaces, screaming toddlers, bad marriages, money problems. Our bodies aren’t built for that. If you have the tiger at your doorstep for years, then all kinds of internal mechanisms break down, from sleep rhythms to specific parts of the immune system. Enduring chronic stress is a little bit like taking a giant airplane and sticking it into water. The airplane wasn’t built to be in water; the brain wasn’t built to endure chronic stress."
