When I was a kid I saw an elderly man get hit by a car. He rolled over the top, which I guess is safer than being run down, but he got a lot of air and hit the pavement hard. Just kept rolling over and over. My parents shooed us away from the scene, but I can’t imagine it ended well for him.

One time I was riding a bus that rear-ended a motorcycle. I didn’t see the collision itself, but the driver was pronounced dead at the scene.

We often take for granted how dangerous traffic is. Your life can end in a moment doing something we casually do every day.

I was working in a department store when a middle-aged woman collapsed in front of me. It was really warm, heat exhaustion I supposed. She looked like maybe she was drunk because she was moving kind of erratically, so I went to see if she was okay and she just fell. I’ll never forget the sound her head made hitting the concrete or the fact that she didn’t even blink. Remarkably, she was okay and was up in a few minutes, walked away and everything, really surprised me.

The thing that probably fucked me up the most though was some videos on YouTube. I was working for a video analytics company, and we were trying to build an image classifier that could detect firearms. Well, you need data for that, so we were scraping videos of gun crime. Mostly what we were looking for was armed robbery. Lots of videos put out by the local police of somebody holding up a convenience store, and that wasn’t a big deal. But every now and then you’d find a video of someone getting shot and that really affected me. Eight hours a day of looking at gun crime with the occasional homicide peppered in was a recipe for disaster. I definitely needed therapy after that job.
