My father two years ago had a heart attack and a stroke, I found him and yelled for my mom and sister, then started CPR until the paramedics came. He survived and is doing very well, but it's crazy to think there was only a 10%~ish chance of it working.
So I once made a script with python and selenium to make fake petitions to bring back Wendy's spicy chicken nuggets. It stopped around 9,000 when the script crashed after awhile... I think they did bring it back though so I feel like I was responsible.
