Glad you like my statement

I got to agree with Silvio on the point of physically (or psychologically) more difficult jobs. There must at least come a clearer seperation between different branches of jobs.
About the life expectancy and use that as a measure for the possible raising of the retirement age, I don't know if it would really work, because there sometimes happen to be fluctuations in life expectancy. But I do think it might be a good idea, if the average age does get higher.
A point of the retirement I don't really understand is the ones for people in the army/in the marine/navy and such. They can retire quite early, because of the job, and even sooner if they have done some certain shifts. For example, my great uncle had a job at the Navy, at which he did some years in the Tropics (that counted for 'double' years), so he could retire at about 45. He is now 93, so... he is one of the exceptions who has had a longer retirement than working time

, so about 30 years of working, versus 48 years of retirement.
I don't know what you think, but there is a certain discrepancy here...
