I was about to scroll past this submission when I had a sudden attack of superstition that, if I don't read it, I will eventually find myself on a sinking ship in the middle of the ocean and curse myself for not reading the damn HN article.
It's like when you're studying for a test and fail to study that one topic cause you think it's never gonna show up, only to find that not only did it show up, it ended up being 20% of the entire test.
Oh wow I do not miss school.
There are some things you should study even though you will never need it. Getting out in a fire, first aid/CPR, earthquake procedures... You need to know these well just in case.
