I worked with a small crew of 8 in a large company. When I left, the company hired two to replace me. (long overdue) Both were my friends and I counseled them to take the job. One died from a heart attack at 49 a year later, and the other friend another 6 months later at age 60, again heart attack. And then within a few months another worker in the same dept. died of a heart attack. All from a small crew.
At my retirement the personal dude said I should consider myself lucky to go at age 49 cause the average retirement in my company was 7 years.
