I of course used the other brake. The problem was that I was going downhill trying to do an emergency stop with brakes on opposite sides to what I was used to.

I broke my collarbone because of this. I was a mountain biking enthusiast throughout my childhood and youth in Australia where the front brake is on the right. Fast forward to a couple of years ago, I’m riding a bicycle down the street in Vienna and 3 people walk out in front of me from between parked cars. I instinctively grab a big handful of the left brake lever thinking it’s the rear brake. It’s the front brake.

I fly over the bars and land on my shoulder. Broken collarbone ahoi.
