Saying he died due to age, 61, is like someone would say: AF 447 crashed because pilots were stupid or Scarebus is a crappy plane. It shows luck of common sense and respect for a fellow human and crew member, also a lot of ME...ME....ME and only ME. After ME the hell can broke loose.
Someone gave the 2007 Continental example. The pilot was 58. Should that be taken in consideration? Or the co-pilot who died on me at only 32. Why not consider 30 years old the limit? As long as you can hold a medical you should be good to go. Once someone is born, sooner or later will die. How and when will always be an enigma. The best we can do is to try to take care of ourself and cheat the death for a longer period of time. That's another reason why there are 2 pilots on the plane.
