..."Our brains are wired for survival. In prehistoric times, humans knew enough not to wander into an unfamiliar cave. It wasn’t the enclosed space our ancestors feared; rather, it was the uncertainty about what lurked within.
This fear of the unknown was passed down through the generations and is still with us today. During times of uncertainty, our sense of fear is heightened, leading us to follow a safer, more comfortable path — or no path at all."
