Even 80 isn't all that old these days. All 4 of my grandparents lived until 78 (cancer,) 85 (multiple cancers over a 20 year period,) 88 (heart attack) and 92 (broken heart, loss of the will to live.)

On the other hand my mother died at 55 due to cancer nearly 11 years ago.

However if someone passes in their 80s or 90s, I think everyone can agree that they've lived their life, it's not really an early life. My Fiance feels very cheated that her Father is gone at 69. We all do feel cheated.
