I remember going to Kenya years ago. I wasn’t hunting but got to see some wild animals close up in the Maasai Mara National Reserve. My girlfriend and I had rented a little Suzuki jeep. And there was nobody monitoring us. You could drive right up to a group of lions snoozing in the noonday sun, and they wouldn’t even acknowledge your presence. I remember having my girlfriend edge the car ever closer as I watched from the open sunroof, my head and shoulders well outside the vehicle. At a certain moment one of the lions rolled over a little bit. Not much, maybe a quarter-turn. But as it did so, my lizard brain finally kicked in. Because I knew that the animal, which had barely moved, had nonetheless activated its body. Further, I knew without the slightest doubt that if this lion had wanted me, it would already have my head in its jaws. That it could cover the distance from its prone position to my head—8 feet above the ground and about 15 feet away—faster than I could drop back into the car.
