Around 45 to 50 years old, systems administrator, who had a heart attack. Did some work in the server room, but nothing strenuous as far as I know. I've worked in a number of buildings with 4 to 7 K employees, and with that large a population, heart attacks and strokes happen. People also have mental breakdowns, although they are usually not dangerous. Smaller locations with 50 to 100 young employees probably never experience it.
