I grew up in Alaska, where one thing after another was constantly threatening my young life. Floatplanes stalled. Grizzlies ate our camping supplies. A moose wandering through our backyard got angrier than expected when a kid from school threw a rock at its knees. I wouldn’t say I was cavalier or brave about these experiences, but I didn’t need much time to recover from them. I was a child. My conclusion was almost always the same: I was still alive, and so was the rest of my family. We could all eat a granola bar and keep on fishing.
