What age is a “good” age to die?

You’ve all heard it. Bob died, he was 65. Damn, he was still so young, that’s a damn shame. Hell, another example. Jeff passed away at 78. He still had so much time left, had a lot more years, etc.

At what age do you think most people would say, “They lived a long life, it was their time”. I know the life expectancy is somewhere around 80 right? So if you die before you reach the age of 80, did you die a premature death?

At what point do you think is an age where you can feel that you lived as long as you could have and have peace with that?
