^ totally right, fairy.
My uncle died two weeks ago aged 88, he was the older brother of my father, there's another uncle/brother now aged 84, and my father is 80. The whole family was like "uuuh, we did not expect that" - although the uncle was fragile for the last 5 years already. So dying peacefully at 88 (after having lived a good & full life in mostly good health, seeing your 2 sons having 4 kids themselves), is, in my eyes, a natural thing.
We do often forget that the current live expectancy, as reported, does not apply to those born 80 years ago.
A man born today may in average expect to live for 80 years.
At the time my uncle was born (1931), the life expectancy for males born it that year was around 63. So when you surpass this by a quarter of a century, I think that's an achievement per se already.
Sure it is always a tragedy when a family member passes away, but at least he died peaceful at home and we all had the time to say goodbye.
From this point of view, also Konstantin is way above the average already, and looking at pictures from the past years, he has become really frail recently.
