Yes, life is not fair. Sounds like he was appreciated by family and friends.
Thirty years ago, I was working after hours trying to graph some reports which were due for a meeting on Monday. A great guy who worked nearby on the floor, but only casually knew me, stayed to help me out to understand a new color printer. He didn't have to, as he had nothing to do with my assignment.
He was in his mid to late 40's, and maybe 50 pounds over weight. Very pleasant guy who always seemed very calm. Sadly when I showed up at work on Monday morning, I heard that he passed away from a heart attack. I was shocked to say the least.
