I work on an app that's pretty complex and requires a lot of back and forth between devs, customers, and the people who do all the training/sales. I've had A LOT of success using numbered bullet points instead of writing normal sentences and paragraphs.
Something about the numbers makes them want to read it in order instead of skimming and it being broken down and labeled lets me respond with things like, "great, what about the 3rd bullet point?" Instead of having to repeat things. Plus most of my coworkers are in Texas so they love bullets.
I looked it up before making the comment and the first result said it was drowning while on duty and car wrecks off duty
