When I was in Canada one guide gave us an important piece of advice about bears: “Black bite, brown down”. In other words, black bears can be intimidated (unless they’re with their young or cornered), so make lots of noise to repulse them. All you can do with brown – or grizzly – bears is make yourself as small as possible on the ground and pray they may lose interest. Good advice for the workplace? Not all of us are bear whisperers.
