“And you are assuming that firstly that increasing life expectancy year on year is just to be expected, and secondly that the sole cause is working longer, not any other of the myriad health related problems.”
Err, no. I didn’t assume that life expectancy will always increase. What I was not expecting was to be shorter…
Then, the only circumstances in the 8 countries have in common is the increase of the working life: Because, in fact, we are better treated in Europe than we never have been: Better food, healthy life, social welfare, health and safety things in workplace, no more children in factories, less pollution due to no more old fashion industries, better life…

“My Grandfather worked until 70, Grandmother likewise - my father is still working at 61...” My grand-father died at 55, my father at 51. There are no male from my family who crossed the 60. My uncle might in few years, but notice he was an engineer, whereas my grand-father worked in the Railways and my father was soldier then worker… Oh, wait, perhaps there is a cause to effect factor…

“The suggestion that people become useless at 60 because they are not longer able to work is not only absurd but also offensive and docially divisive.”
For you the only use of human being is to work? You live in a strange world.
Sorry, I have other dream for elderly people than to work until they die. The time to walk with the grandchildren, to share with them a part of the journey, or with the nephews and nieces… Small pleasures, ambitions fulfilled, to enjoy a sun set, when you look behind and have the time to share, building memories to your younger family who, if you are lucky, will remember me like I remember my grand-father and father I had to know so shortly.
I gave to my country time in the Army, I worked all my adult life (and I am still working), sometimes for nothing as a volunteer, I am not asking for a favour. I am asking the State to fulfil the contract I signed when I paid my taxes and my pension.

“Someone who believes a Greek collapse will lead to a global collapse has left reason behind.” Explain how it will not? I gave no the reason it might if wrong decisions are taken. Tell me how the collapse of 5 major banks in France and Germany will not shake the system and can’t produce what I am saying?
The Collapse on one Currency in Germany produced a War, if you remember… Or learn.
