Clash between our genes & environment

Our genome is out of equilibrium, both with itself and its environment. Simply put, our genes aren’t coping well with modern culture. Our bodies were never designed to subsist on fat and sugary foods; our immune systems weren’t designed for today’s clean, bland environments; our minds weren’t designed to process hard-edged, artificial electronic inputs from dawn ’til midnight.
