I headed back to Shun Tak to catch the next ferry to Macau. I tried not to think too much about what I was about to do. Charging an ambush is counterinstinctive: when your lizard brain identifies the direction the threat is coming from, it wants you to run away. But your lizard brain doesn't always know best. It tends to focus on short-term considerations, and doesn't always adequately account for the value of unpredictability, of deception, of surprise. Of taking a short-term risk for a longer term gain.
