I had a student who worked for a major company here drop dead of a heart attack on the job, The guy was a mid-level manager in his early forties. I also noticed at the companies I've taught at that they all have large smoking areas that are completely full whenever there is a break.

And I've heard Toyota, Mitsubishi, and a few other big companies will ask ambulances to turn off their sirens if someone drops dead at work or commits suicide when they come to collect the body.
